Projector and Halo Style Headlights

Have you noticed the small round (2 inch to 3 inch) headlights on many new
cars? Did you wonder what these are and why they are being used?

Several years ago high end and exotic cars started using these small
lights, and a new style was introduced that soon other manufacturers began
to follow.

The small lights are called projector headlights, because it uses a small
bulb and “projects” a beam of light down the road. While they look small
compared to the old sealed beam head lights or the newer headlights with
replacement bulbs, the projector style actually can produce up to 30%
better lighting. It is a smaller beam and more concentrated.

Some projector lens HID or high intensity discharge bulbs. These produce
even more illumination, but usually with a blue cast to the light.

A number of aftermarket products are now coming out and offering owners the
ability to replace their stock headlight fixtures with the latest style of
projector lights. You may have two different choices with aftermarket
products. One would be a pure projector and the other a projector with a
halo light.

The halo version of the projector style puts a light ring or halo around
the projector lights. So at night you see the bright projector lights and
“floating” around them is a halo of light.

Just like the earlier Altezza tail lights, the new headlights may have a
lot of chrome around the lights.

If you buy aftermarket projector lights they can be plug to plug compatible
with your existing lights. Thant means that you remove the entire headlight
fixture and replace it with the aftermarket one. All you need for
electrical connections is to unplug your original lights and plug the wire
and plug into the new projector fixture. One caution, however. If you
choose to purchase halo lights, regardless if they say plug to plug
compatible, they probably are not. This is because there was no circuit for
the halo lights in your OEM fixture. You will have to splice the halo wires
into an existing set of wire. Typically people splice the new halo wires
into the parking light circuit of their cars.
