Halo LED projector headlights first appeared as aftermarket parts, available only for certain car models. But by 2011, halo LED projector headlights became available for almost any car make or model.
Halo LED projector headlights consist of two main components: daylights and night-lights. Halos and several LEDs are used as running lights in daylight conditions, while projector lights composed of light bulbs and lenses serve night driving conditions.
The brightness of the LEDs makes your vehicle easily visible in all lighting conditions while the halo adds a more striking look to your car. The projector light prevents the light from scattering in every direction, focusing it on the road and giving you better visibility.
If you plan to replace your stock headlights with a pair of halo LED projector headlights, make sure that what you buy is street-legal, so you won't run into trouble with the police. Aftermarket parts are also built for "show-off cars" and are not always intended for street-use.
