Motorcycle LED Lights?
The Federal requirement is for a white headlamp. The Tennessee code is for red stop and tail lamps. The TN code forbids the combination of red, white and blue light except on specified vehicles, which means in practice that blue lights are illegal, whether they flash or not. However, the same prohibition does not appear to extend to green lights, or, indeed to purple1. What reasons led to the discovery of salt?Given that the creatures that man descended from were not yet human. It's hard to say the exact time , place and by who/what it was that discovered it. However given that over 70% of the earths surface is covered in salt water I imagine that it was connected to the shoreline of the ocean and a walk along the beach. (?).2. What led to the Jordan-Palestine war (1971)?For the full story and many other relevant factors, please check this link: "Black September": The Jordanian-PLO Civil War of 19703. What was the decisive event that led the US to withdraw from Vietnam in 1973?it became obvious to US/other oppossers of vietnam sides, that they would have to withdraw,most boys to elders in Vietnam who could hold a gun were fighting and dying, Vietnamese were NOT going to give up their country,neighboring countries came to their aid:what the US learned was that girls/women were being armed/trained to fight if not enough boys/men would be left, as countries which usually are not in wars showed up to stick up for Vietnam, the US was losing more and face... it was looking like WWIII would arise if the US continued to be bullies...4. what kind of LED bulb do i need for these tail lights?Usually tail lights are single or double filament 12v DC bulbs, therefore you can go to any car accessory automotive shop and they should be able to help you in 95% of the cases either for a new fitment of a tail light bulb or any advice you require with reference to LED bulbs.5. What factors led to the decline of the Ottoman Empire?Decline Of The Ottoman Empire6. Different led voltages for different colorsGoing by the comments, the goal OP has in mind is to have 3 different LED colours that will turn on at different voltages. A way to do this is to use a comparator circuit like this: simulate this circuit - Schematic created using CircuitLabSo in this circuit, when Vin gets lower than Vref, the op-amp will output high and turn the LED on. This should get your started towards coming up with your own circuit. A good beginners read on comparators can be found HERE which goes through the types of comparator circuits and how to use them.All you need to do is edit this circuit to do what you want. You can have multiple reference voltages at 2V, 3V, 4V, 5V and so on that toggle on different LEDs at different points. You can either use multiple LEDs, use an RGB LED, or whatever you like. This answer should provide you with all the information you need to start designing your circuit, while not doing all the work for you7. Blinking led using interrupts in AVRThis is the ATTiny13's interrupt vector table. PCINT3 is not an interrupt vector. You need to change that to PCINT0. It looks like you have the PCI and mask set properly. You should be able to make that change and have your interrupts work. You also need to add initialization to make your push button work.That will enable the internal pull-up and allow an edge to happen on a button press. This will likely work for simulation, but a real circuit will need some debounce either in hardware or software.8. Transformer for my LEDThe main reason they do not carry them is because there is no demand for them9. is it possible to sew led lights inside your shirt?just consume zinc sulfide and strontium aluminate then you will develop Phosphorescence10.

Are the Colorful LED Lights Illegal on a Motorcycle?
yes, it's illegal to have lights on while riding, but cops rarely stop people for it1. What size belt will the holster that comes with the Mini-mag led 2aa accommodate?That light's not bright enough for duty. Walmart has some Coleman ones that are pretty bright (115 lumens) for under $30, but you would need to find a holster for it if you do not want to carry it in your pocket. It also has a tailcap button that does not need to be pressed all the way down, so it's easier to operate in most situations. I've had mine in a jacket pocket for the past 6 months or so and it's still going strong (I've killed two husky flashlights in about the same timespan). Also, if you can make or find an oversized D-cell maglight ring, Husky has a ($30) 200 lumen "tactical" flashlight that's pretty hefty (Home Depot carries it).2. Why has the opposition led a no-trust motion against the Modi government?Technically its not opposition its TDP the previous ally of NDA/BJP requested or moved it. The opposition in Parliament has no will or strength to counter modi with a no confidence motion, but its the congress which was behind this destructive idea. It suggested TDP to go for a no confidence motion in LS to check the progressive moving of Modi as Congress lost the hope of winning 2019 elections. It wants to find the new partners for the 2019 elections so the person who united the regional parties earlier Mr. Chandra Babu Naidu was put in front so that the other parties will come under the umbrella of Congress and fight Modi.Congress and TDP want to ally for the forth coming elections in AP and Telangana, in other states where the regional parties are reluctant to work with Congress, CB Naidu want to bring them to congress for an understanding. To achieve this they found nothing but a no confidence motion which attracts a national level attention.What will be the result of such moveTDP is going to lose its moral grounds as the center will counter TDP leaders in LS & RS with the facts as they are now well prepared for it.Congress will get back the same reputation that it neither cares for the welfare of the nation nor let others work for the nation. Congress gets more isolated and its allies take this opportunity to desert Congress for next elections.As my fellow quoran already said its Vinasakale Veeparatha Budhi which means when the bad time approaches decisions will be made to result in fatal3. Has love ever led you to madness?My man says, "and then some". He is engaged to me..so...well..do the math.4. Is it a problem to overload an LED?It will burn out faster. Give it too much power and it will stop working in a second5. car LED lights?yes they make them .. the use way less power but put off more light . they do not build heat , like bulbs do6. What MLB player led the majors in hits in 2004?Ichiro Suzuki of the Seattle Mariners set the Major League record for hits in a season with 2627. What led to Gaddafi's death?His reason for being killed is pretty complicated , but it could be sum up in two point: he's a victim of some widely speculated crimes and his death is the result of the American impulse , I will address the following points:Speculated crimes:Now I could bet that nobody have the evidence that General Gaddafi order any mass rape or rape anyone himself , no evidence was made public , nor was there any claim that Qaddafi had been connected to such event , yet peoples believe them , fanatically , this is just a way of justifying the western motives of killing General Gaddafi , and It's not even a proven way , but in a logical sense , if I am General Gaddafi , I would try to maintain supports among my peoples since the whole world turn their back on me , not terrorizing my peoples. The American misunderstanding of the situation and their malicious attempt for war: About five years ago , the Warhawk in president Obama cabinet has chosen to enforce a no-fly zone , Its purpose is to "protect" Libyan protesters , whom decided to publicly oppose to president Gaddafi at the height of the Arab Spring , and possibly undermine president Gaddafi by the U.S their allies NATO military intervention , they've initially succeeded , but things did not turn their ways as times go by(or is it?). Gaddafi was a great man , he's a great Socialist , his death is a very unfortunate event considering how much accomplishment he have and what he has achieved for Libya , he may die but his legacies will live on , Libya in Gaddafi image (or close to it) will return someday

Led Lights for Your Pool
Many people enjoy lighting up the outdoor areas of their home throughout the year, and not just at Christmas. A beautifully lit lawn, deck, and pool area can provide the perfect setting for a backyard barbecue, outdoor wedding, or summer party. But decorative lighting doesn't just have to be brought out when your guests come over. Adding a little mood lighting can quickly turn your backyard oasis into a true refuge. LED lighting is becoming a very popular choice for lighting pools of all sizes. Because of their long life and efficient energy use, LED light bulbs are quickly replacing other, older forms of lighting. Not only does the long life of an LED light bulb mean that you spend less money on replacements over the long-term, it also greatly reduces the inconvenience of replacing bulbs in hard to reach or inaccessible places. LED lighting also creates a directed stream of light, with several colors available, that makes it ideal for use underwater. With so many new LED pool products available, you are certain to find the right fit for your pool, whether a fully in-ground or an above-ground, vinyl sided pool. If your pool is used after dark it is essential to have good lighting available for safety without creating harsh spotlighting that will ruin the magic of night swimming. LED lights that hang on the side of your pool are a great way to light up the area to keep everyone safe, while at the same time keeping the lighting soft and discreet. If you want to add lighting to your pool for more decorative purposes, LED lights are available in several colors in various products. Illuminated roses can float over the top of the pool, or you might try colored underwater lights that create various color and strobe lighting effects. Regardless of how you want to add light to your pool, you are sure to find an LED pool product that suits your needs.

Do You Have Led Lights on Your
we got them last year for our tree inside and YES they look like Hyper White Car lights!! Needless to say they are not up this year...really did not like them!1. What Are The 7 Best Pool Lights? **Updated 2021**Need a new light for your pool and do not know what to get? Let's take a closer look at the best pool lights on the market right now, and how to pick one that works for you. Our Picks For Best Pool Lights We searched high and low for the best pool lights across numerous categories, narrowing it down to just a select few. Best Light For Above Ground Pools It's safe to say pool lighting is well worth the small upfront investment, but like anything, lighting up your swimming pool has its pros and cons. Opens your pool up to evening or nighttime use Gives color and life to your pool water (some through beautiful light shows) Combos well with water features (like waterfalls, scuppers, or grottos) Improves visibility and prevents others from accidentally falling into the pool (such as children or pets) Lights designed for pools are 100% safe to use in the water (no electrical dangers) You can spot dangerous wildlife (e.g. snakes) sneaking into your pool Some lights can be remote controlled for more convenience There's an upfront cost (like almost all pool stuff) Both lights and fixtures may need to be changed in future They are covered up by regular covers or solar covers You will come across various types of pool lights when shopping around, so it's important to know what they are and how they differ. LED (Light Emitting Diode) pool lights work by channeling voltage through a semiconductor (the diode) which then emits light. They are not always the cheapest option, but LED lights are very much plug-and-play once hooked up to a power source, lasting many years, running cool to the touch, and using very little energy in the process. This type of light is also great if you want to make use of different colors, as they can be pre-programmed to stay on a variety of colors or even scroll through them in a dazzling sequence. LED pool lights are now by far the most popular type on the market, as they should be. Unless you have a specific need that LED can not fulfil, this is the go-to option. Fiber optic pools lights are fundamentally different because the bulb itself is located in an illuminator (also called a dry box or lightbox), which is installed outside of your pool, away from the water. The light from the bulb is then transmitted through a thin, flexible cable (optical fiber) that feeds into your pool, and specifically into your pool wall via a special fitting. This light then reaches the end of the cable, lighting up your pool with the help of a lens. Being able to easily change or fix your pool light without touching the pool is one of the obvious benefits to this setup, but they are also fairly versatile because the cable can be fed into virtually any point or position in your pool. They can also be programmed with different colors, like LED lights. With that being said, fiber optic lights are noticeably weaker than LED in terms of light output, do not last nearly as long, and can sometimes even be more expensive. That's why you do not see them being sold nearly as often these days. Halogen is basically an enhanced version of incandescent lighting, as an electrical current is used to heat up a filament to the point where it emits light. There's actually a lot going for halogen pool lights. They are cheap to buy, they are brighter than most other types, and they are installed in an enclosed fixture that makes replacing them easier than replacing LED lights. A pool light fixture is the housing that holds your light in your place, so let's talk about how those come into play. Inground pool light fixtures come in two types, flush-mounted and surface-mounted. Flush-mounted light fixtures are installed during the initial build of an inground swimming pool, positioned underwater, clearly visible on the pool walls and pool steps. As their name suggests, they are fitted directly inside the walls (in what is called a "niche") so they are perfectly flush with the wall. Here's where you need to be careful though. Different lights fit different flush-mounted fixtures, so if you are simply changing your old bulb for a new one then you better be sure it's compatible with your fixture. Of course, if you are certain you want to convert to a different type or brand of pool light, you may be required to change your fixture entirely. Ultimately, it's impossible to say if any given light will fit your current flush-mounted fixture without knowing your current setup, so it's important to read the documentation for both before making a purchase. Surface-mounted light fixtures are less common, but often used in the absence of flush-mounted fixtures at a much cheaper cost. They function the same way as their flush-mounted cousins, except they are retro-fitted to the wall surface making them very slightly raised from the wall itself, but also far easier to install. For example, this one below uses a bracket to connect the light to the wall, and all the necessary electrical components exist inside the light itself. Another variant of this relies on magnets. These are essentially waterproof LED lights combined with magnetic fixtures, otherwise called magnetic pool lights. Do not you just love the creativity in this industry? The fixtures themselves attach to the walls through suction cups, and the light attaches to the fixture using the magnets. They can also attach to the metal frame of an above ground pool. Speaking of above ground pools, while magnetic lights are a viable option there are other types of fixtures that are specifically designed for this type of pool, including Intex pools. For example, you can use a wall mounted light fixture. This one hooks over the edge of the pool with the actual light/lamp positioned underwater. Extremely easy to set up, but a little bulky in practicality. A better option for above ground pools is to install a specially made return fitting that includes a halogen light, though you will need a transformer to power it. This thing replaces the original return line fitting on your above ground pool, the same one that your filter uses. It's pretty straightforward with no cutting or modding involved, and it works well. Floating pool lights, or "floaters", work with inground, semi-inground and above ground pools, as they sit freely on the surface of the water. Unlike most other pool lights, they do not rely on fixtures and are generally complementary to a more permanent lighting solution. The vast majority of floating lights you come across will be LED lights, however, they are not nearly as bright due to their cordless nature. Instead, they give off more of a glow for aesthetic effect. Some are purely battery-powered, meaning they need to be recharged for continued use. You can get anywhere from a few hours to a few days depending on brands, size, brightness and daily use. Others are solar-powered, meaning they use the sun's rays to charge themselves during the day, so they can be used at night without any additional power. Many solar floaters will hold enough charge to make it through the night. What You Need To Consider Now let's talk about the most important aspects and features to consider when it comes to choosing lights for your swimming pool. Does The Color Of The Light Matter? Some pool lights only emit white light for a classic warming effect. This works great if you want something simple or your focus is mostly on safety, but it does not give you much room when it comes to mood lighting. Many LED pool lights (the type we recommend) can output various colors such as blue, green, red, and everything in between - including white, so it makes sense to get a light that leaves all options on the table. After all, being able to change colors or dim the lights can really add an extra dimension to night swimming. It's also no secret that you can achieve some seriously stunning visual effects and water colors with the right tone of light, especially when paired with different pool finishes and plaster colors. Do You Need A Remote Control? Many pool lights will come with a remote control to adjust the color and brightness settings wirelessly, and some even allow you to use a smartphone app. While a remote is not an essential accessory for every type of pool light, the convenience factor is real and it's certainly worth going the extra mile to get a light that comes bundled with a remote control. Just check before buying that the remote uses radio frequency (RF) instead of infrared (IR) because the range and effectiveness is much higher with the former. The only downside to remote controlled pool lights is that some can only be turned on and controlled with the included remote, so losing it can render your lights useless until a replacement is found. Should You Pay Attention To Wattage? For less commonly used types of pool lights, like halogen lights, you can get a pretty accurate gauge on the potential brightness by looking at the power output (or Wattage) for a particular bulb. Nowadays, however, with the rise of power-efficient LED bulbs, Wattage is not nearly as reliable for understanding brightness. Instead, a better way to measure brightness is by looking at Lumens - which is the direct measurement of light output. So if you need to light up a large pool, large area of your pool, or you have a dark interior finish that absorbs more light, you will want a bulb with a higher Lumen output even if that means higher Wattage and more power consumption. On the other hand, if efficiency is important to drive down your running costs, the best way to approach this is to find a bulb with minimal power usage (Watts) and the most light output (Lumens). Do You Care About Attracting Insects? We all know light attracts insects, so it's not surprising to learn that swimming pool lights attract insects to your pool. It's simple: the brighter your pool lights, the more bugs (and even potentially animals) they will attract. Of course, that will be of little concern if you are not using the pool after dark, but it's a whole different story if you plan on sitting or standing near the pool, especially when hosting gatherings or pool parties. The best way to counteract this pest problem is to position your lights away from parts of the pool where humans are likely to congregate. If insects persist, it's a good idea to check your water chemistry and stay on top of algae growth, as most light-attracted insects feed on algae (not humans). If all else fails, consider a pool enclosure. Do You Need Lights For Your Landscape? Many of the surface-mounted lights we've covered can even be used for your coping, decking or patio, as well as various other landscaping features. For example, while technically waterproof, the magnetic LED lights can be pinned to virtually any fixture and operate above-water to the same effect. Or you can get real creative with floating pool lights, sprinkling them around your lawn in various colors. I mean, you do not even need a swimming pool to make this work, it looks great regardless. And, of course, if you use the solar-powered versions you will never even have to worry about charging them up again.2. What store sells colored LED lights for vehicles?uh i see most of led lights for vehicles are white, yellow and red..but purple? i've already learned something today hehe
LED Safari: Teaching People to Make Solar Lights
There is a proverb I'm sure you've heard before that says "give a man a fish and you feed him for a day; teach a man to fish and you feed him for a lifetime." LED Safari is doing just this, going beyond providing affordable solar lighting to teaching people to make solar lights themselves. Today there are many organizations that are spreading solar power to rural areas in developing countries. The new range of options and prices has made solar power increasingly accessible to poorer households. However, there is still a barrier to the poorest, who are unable to take the risk of investing in a solar lamp that could break. They feel safer continuing to spend the same amount on kerosene, even if the lamp would be cheaper in the long run.LED Safari began in 2010 with a plan address this concern. They train people to make their own lamps out of the main components. This not only allows people to be creative in the design of different lamps, but also ensures that the lamps can be repaired if they should break. The model also provides people with valuable skills and empowers them to create unique businesses making different kinds of lighting products, or repairing them when they break. In addition, solar lamps can be made out of just about anything, so this program is promoting a new kind of upcycling.To date, LED Safari has trained 300 people and produced 1,000 lamps in Rwanda, Uganda, Kenya, Tanzania and India. Their program is providing skills, creating new entrepreneurs, and making solar power more accessible to the poor. LED Safari also conducts workshops in developed countries for schools, companies and other organizations interested in learning about solar power or looking for a great team building activity.

Controlling LED Lights with Arduino
I am beginning to see the power of Arduino and the potential it has even for someone like me who is totally new to it. With the right tools, controls, and creative ideas Arduino can used for serious prototyping of any type of physically interactive product . Even as I write this, I am thinking of the capabilities for it to be used in the health industry.In my last class we gained more practice wiring circuits. We learned the difference between serial and parallel circuits. Do you remember the time when one bulb on a string of your Christmas lights would go out and as a result all the rest of the lights didn't work? Well that was because they were manufactured to be in a serial circuit. In this way the circuit was broken with that one bulb which meant the electricity could not have a continuous flow. Pretty cool right? Who would have thought I would learn about electric circuits and how to create them in a design program.After wiring up a circuit with 4 LEDs we wrote the code to have them light up in a series one after another, and then to reverse. We were able to program the speed at which they would light up, and after adding a control we could control this speed with a little knob. We were also able to write the code to control the brightness with this knob as well. Technically I now have the knowledge create some pretty cool custom Chrismas lights.Here's a video of my LED circuit:Here is the code for the flashing lights above:/program to make a series of pins light up one at a timeint ledPins[] = 13, 12, 11, 10;void setup() /set the pinmode for all the pins for(int i=0; i=0; k--) digitalWrite( ledPins[k], HIGH ); knob = changeSpeed(); delay( knob ); digitalWrite( ledPins[k], LOW ); /end of loopint changeSpeed() int knob = analogRead( A0 );/get knob position/map it to the speed knob = map( knob, 0, 1023, 50, 500 ); /speeds will always be between 50 and 500 return(knob);Here is the code I to control the brightness using a knob:/program to change the brightness of the pinbased on the knob.int ledPins[] = 11, 10, 9, 6;void setup() /set the pinmode for all the pins for(int i=0; i=0; k--) analogWrite( ledPins[k], knob ); knob = changeLevel(); delay( 500 ); analogWrite( ledPins[k], LOW ); /end of loopint changeLevel() int knob = analogRead( A0 );/get knob position/map it to the speed knob = map( knob, 0, 1023, 0, 255 ); /Level will always be between 0 and 255 for analog Write return(knob);·RELATED QUESTIONWhat are some of the cleverest inventions and ideas ever?
