Blue tinted headlights can create a customized look for your vehicle as well as increase night time visibility. Some blue tinted lights are supposedly brighter than regular headlights, but it depends on the wattage of the bulb and how the blue coloring was added. In some states, blue tinted lights may be illegal, so it is important to check local laws and regulations before installing blue tinted lights on your car, truck or motorcycle.
High Intensity Discharge Xenon lights work differently than traditional headlights. The HID light bulb holds xenon gas, along with several other chemical substances. When it is lit, it creates a bright glow that is supposed to be brighter than that of traditional headlights. You can typically recognize HID lights by their blue glow, but they are not truly blue. Rather, the blue tint is the result of the way the light reflects and refracts as well as the Kelvin temperature of the bulb, with white being the hottest bulbs. HID lights come standard in a number of luxury vehicles as well as some domestic models. There are also conversion kits available to allow a vehicle with non-xenon headlights to use HID headlights.
If your vehicle does not have HID lights, you can get blue tinted headlights by installing a headlight bulb that was manufactured to have a blue coloring when lit up. Several different manufacturers make these bulbs, and they are advertised to provide better nighttime visibility without blinding other drivers on the roadway. These bulbs are also the most likely to be legal to use in a car or truck, as manufacturers will have already taken most commonly occurring nationwide laws into consideration before producing the bulbs for mass sale. These bulbs are designed to mimic the effects of HID light bulbs, without actually being HID bulbs.
Some people will attempt to create a blue light effect by applying a light layer of blue tint or wrap on the existing headlight. This does create a blue tinted light, but may not be legal in many areas and should probably only be used on vehicles that do not travel on regulated roadways. Off-road vehicles and show vehicles may have this done for looks. Adding a blue tint to your headlight may reduce visibility by darkening the light coming from your headlight.
