Nowadays, cars come with different types of headlights. While yellow and white lights are pretty common, blue headlights seem to be a new and exciting trend. They give the vehicle a unique look and make it stand out on the road. However, there are other types of blue headlights, and not all of them are legal. So, what are blue headlights and are they illegal?
Today, we will give you a complete guide about blue headlights, covering all the headlights that emit blue light, their legality, benefits, and potential risks associated with them. So, let’s dive in!
The way they work is quite interesting: Xenon headlights create light by forming an electric arc between two electrodes inside a quartz bulb containing xenon gas.
Xenon HID bulbs are specifically designed to produce a blue tint because they emit more blue wavelengths than other colors. This concentrated spectrum results in short wavelengths that are highly visible to the human eye. It significantly enhances brightness and clarity. For your information, this principle is similar to the light emitted by computer screens and cell phones. These devices also appear prominently blue to the observer.
You have to note that while halogen bulbs emit a white-tinted light with all the rainbow colors, the blue wavelengths in xenon and aftermarket HID headlights make them stand out distinctly. However, these short blue wavelengths can cause visibility issues for other oncoming drivers.
