The technology allows the driver to turn on their high beams when their headlights are on. The DOT-compliant embossed sticker or logo does not mean that the headlights or products you buy are truly DOT compliant. According to the National Highway Traffic Safety Administration (NHTSA), “THE DOT does not approve motor vehicles or automotive equipment that comply with all applicable FMVSS. Rather, it is the responsibility of the original manufacturer of the vehicle or equipment. All motor vehicles in Texas must have two working headlights that are white. It is also important that your headlights are not masked by a lid or grille. Bulbs must bear a “DOT” stamp or an equivalent SAE stamp. This only really becomes a problem with some aftermarket lights that are not equipped by the automaker. Mark Baker of Softlights.org sent an email to The Columbian stating, “There is clearly a conspiracy by the auto industry and those who are supposed to regulate the industry regarding these eye-damaging LED headlights.” Headlight technology has come a long way, from acetylene or oil lamps in the late 19th century to sealed headlights with a large assembly, to the introduction of halogen lamps in the mid-1980s.
Headlights allow drivers to see where they are going at night and other drivers, cyclists and pedestrians to see them. With the growing popularity of light-emitting diode or LED headlights, some are wondering if today`s headlights are too bright. “Does this mean that state and federal standards allow headlights to be too high? Super blue halogen: Blue or super blue halogen lamps also produce white light. Avoid installing equipment that interferes with the efficiency or color of your headlights or taillights, and make sure your license plate is free of decals or covers that hide the letters and numbers on your badge. Note that motorcyclists should use both day and night lights to improve their visibility on cars and trucks. Similarly, cyclists should have a light on the front of their bike at night and a red light or reflector on the back. If you`re not so sure, look for reviews of their products on Amazon, eBay, YouTube, and forums for the vehicle you`re looking for. Typically, projectors under $100 that you see on marketplace sites like Amazon or eBay won`t meet dot regulations and will likely perform very poorly. So you can definitely install “blue” or “super blue” headlights because the wavelength of the light is actually white. However, no other color can be used.
There is evidence that some headlights do not adequately illuminate the road for safety reasons. The Lighting Research Center, which is part of rensselaer Polytechnic Institute in Troy, New York, has identified a projector that would be the biggest contributor to excessive glare. The centre assessed headlights targeting more than 100 vehicles and found that two-thirds of the vehicles had at least one headlight that was not properly aligned. Nearly a third of the new cars had misaligned one or both headlights. Vancouver`s Josh Whitehead put the spotlight on as part of The Columbian`s Clark Asks series, in which readers suggest news and vote on which ones should be covered. Newer headlights also create a sharper boundary, a line between light and dark that can be seen when headlights are pointed at a wall or garage door, Flannagan said. The cut-off protects oncoming drivers from being hit by too much light, but it can cause a problem for drivers who meet near the crest of a hill. “If you have a vehicle that has been modified with a replacement suspension, remember that this has changed the original manufacturer`s specifications for the angle of your headlights,” Pennings added. In the United States, lamps, reflective devices, and related devices are regulated by the U.S. Department of Transportation (DOT). Although these types of LED lights can be used instead of an original halogen lamp, it is not legal to use them in vehicles approved for road use. This type of modification can only be made if it is used in a fog light application, a special off-road application or in a jurisdiction outside the United States where it is allowed.

It is important to know the laws of your state, province or country before you fully commit to using LED lights or headlights. It`s just as important that you do your research to find out what is DOT compliant and what is not. Today, we`re going to look at what is and isn`t considered DOT compliant in a broader sense, and look at some real-world examples. This means that they can be used legally. The only colored light that can be legally used in any state is white. This means that you cannot use any other colored light. If the LED headlights you`re looking at don`t advertise that they`re CERTIFIED OR APPROVED BY THE DOT, chances are they`re not really legal to use on the road. As of 2/2022, LED headlights will no longer be legal changes for cars homologated for use on the road or on the road.
If you put a pair of GTR Lighting Ultra 2 in your climbing Jeep Wrangler that you slide on the trail, then you`re all set. Otherwise, it`s not technically legal for headlight applications. David Aylor, director of dynamic safety testing at the Insurance Institute for Highway Safety, said better headlights are often bundled together as part of a package of options that increases the price of the vehicle. Fran Laub, a 77-year-old Vancouver resident, drives a 2003 Mercury Grand Marquis. It generally avoids driving at night, in part because of the glare of the headlights of other vehicles. Flannagan of the University of Michigan Transportation Research Institute said LED headlights with a bluish tint cause more discomfort than older halogen bulbs with a yellow and white appearance. Each state has its own specific laws that govern the legal color of lighthouses, as well as when they should be used. Most states require that the only colors allowed for lights at the front of a vehicle are white, yellow and amber. The rules are just as strict for taillights, brake lights and turn signals. Lowering the maximum height of lighthouses has been discussed for 20 years, but state and federal laws remain the same. Many drivers don`t know that their headlights need to be properly aligned.
And even new vehicles are driven with misaligned headlights from dealerships. Why can`t colors other than white be used for headlights? It is a question of visibility. If you used blue, red or green headlights, you would be less visible to other drivers at night. You`d also have less visibility if you were driving at night, and driving in foggy conditions with colorful headlights would be incredibly dangerous. Many consumers are concerned about whether the headlights they are interested in pass an inspection or are considered “DOT compliant.” If your headlights indicate “DOT” or “DOT-compliant” or “DOT-Approved”, it`s a safe bet that your headlights will be classified as such. However, many brands use this nickname to fool you when they are anything but legal. Many even deceive you about their performance. While there are many similarities between lighthouse laws from state to state, one could say that the devil is in the details.
