In the US, it is illegal to change the type of bulb that your headlights were originally approved for by the Department of Transportation DOT and similar laws exist in most other countries. Approved headlight fixtures have a very sharp projection pattern that keeps the light out of oncoming eyes. In some European countries, HID system are required to be auto-leveling so that heavy loads in the rear of the vehicle do not pitch the light up into oncoming traffic.
For left hand drive vehicles, the right headlight is actually aimed slightly higher than the left to improve visibility on the right side of the road street signs, peripheral dangers…etc while the left side is aimed lower to keep it out of oncoming eyes.
There are also tinted bulbs available that look similar to HID systems. They are not as bright as HID headlights, but they can often be installed legally. Many bulb manufacturers have introduced brighter and whiter halogen bulbs to give buyers a reasonably priced alternative to traditional bulbs. Subscribe on Kindle. Photo: MSVG creative commons.

Foggy Morning. Dolphin Motorsports July 16, at am. Addierun March 15, at pm. I find the blue lights hurt my eyes, even if I keep my eyes along the side of the road. I do not like. Paul March 17, at am. HIDs get a bad name when people install them in cars and motorcyles that are not designed for them and then they hit your eyes. Leveling or not — just an excuse — these bulbs are hated because they emit a blue light like a blow torch and they hurt your eyes.
We hope some day the DOT will ban them. ProModder November 28, at pm. HIDs that come from the factory are not blue. The reflector bowl in the projector refracts the light at the cutoff, making them appear blue, because they are aimed just below eye level so they dont blind you.
The light coming out is actually white. The more you know! The problem is the aftermarket HIDs that kids put in do not know this, resulting in them buying actual blue HIDs that are going to blind you and hurt your eyes, mostly because they are not put into projectors like they are supposed to be.
Terry February 21, at pm. Who authorized the use of these lights? Was there any data to show how they affect different ages of people? These lights are very blinding even when trying to look to the side away from them. There was no need for these bright lights. When you go around a corner or over a hill and they are suddenly there you are blinded.
When people pull up from behind you get blinded by the inside mirror and also the side mirrors. These are not helping they are hurting more drivers and hopefully others will speak up. TopGearUK April 13, at pm. They have them all over Europe and I am guessing most of the comments here are not form europe but the usa because in Europe everyone has them they come with the car.
Plus not many people complain about them here, they actually help. When weather get bad they help to drive through snow and fog. Fixit Man August 31, at pm. I think one reason fog lights are even more yellow than regular headlights is that the yellow shows up much better through the fog or snow. These, I could see absolutely nothing other than some sort of indistinct glare outside the car. Is there any legal action groups working on illegalizing them?? I have heard so many complaints everywhere.
They make night driving very difficult because my eyes have to re-focus… They outlawed tinted windows These should also be. Ken Crompton January 28, at am. I object to these lights also, even a slight frosting from road grit on the windshield defuses the light to make it very difficult to see. These lights are just as dangerous in daylight also, you can pick them out from regular lights from half a mile away. The color also interfers with some traffic signals making them seem like the bulb is out.
Most blue headlight bulbs on the market are either halogen or HID. Sylvania Cool Blue. One factor that can make or break a blue headlight is how much tint has been placed on the bulb.
The heavier the tint, the dimmer the light. The lighter the tint, the brighter the light. A slight blue tint produces a white light, but a darker tint produces a blue light. I loved the way they looked from the outside, but it really make it tough to see the road at night. The light output was minimal and the performance was poor. However, I found that my vehicles that had the high beam separate from the low beam in the headlight assembly one separate bulb for each handled the blue headlight a lot better.
The light output is lower due to the heavier tint, but the color is great.
