Do Projector Headlights Support LED Bulbs?

CFLs have already been surpassed by light-emitting diodes as the most common kind of indoor illumination. It appears that this fashion may soon extend to automobile headlights.

For automotive headlights, LEDs offer a brighter, more effective replacement for HID and halogen bulbs. According to research, over 86% of automobiles in 2019 have LED headlights, up 31% from 2018. However, LED bulbs are still dangerous to use in reflector headlights and can only be utilized in LED projector headlights.

Since the days of the old tungsten filament bulbs, vehicle headlights have undoubtedly advanced significantly. But is it always preferable to be brighter?

Projector Headlights: What Are They?

Since they were originally used in automobile headlight housings in the 1980s, projectors are a relatively new form of housing. They are made of a metal bowl-shaped light source, mirror reflectors, a shutter, and a lens.

In order to prevent other drivers from being dazzled, the shutter is utilized to block errant beams of light. In contrast, the lens is rounded to magnify the light beam. This concentrates it and moves it farther down the road so you can see a greater distance.

Do LEDs Have Enough Brightness for Projector Headlights?

How do LEDs compare to the halogen or HID bulbs that projector headlights have traditionally utilized since their introduction?

The brightness of LED lights is comparable to that of HIDs and may be up to 300% brighter than conventional halogen headlights. So, LEDs can absolutely be utilized as projector lights due to their brightness.

However, the difficulty of LEDs to illuminate a large area has led to criticism. An LED headlight will struggle to project farther out while having a very strong foreground beam, raising safety issues.

Last Words

It's fair to argue that during the past 20 years, headlights have undoubtedly gotten brighter and whiter. We may anticipate this tendency to persist as long as halogen consumption continues to decline.

In fact, Audi unveiled laser headlights in 2014 that they claim have a range twice as great as even the brightest LED.

What do you think—are strong LED lights the future, or do they pose a safety risk? Are there any specific headlight-related laws in your area?
