1999-2001 Acura 3.2 TL HID Driver Side Headlight

These types of lights used to be more popular on most European vehicles, but are becoming common on other makes and models. Projector lights are lights that have a filament located at one focus of a reflector, and a round glass or heavy duty plastic condenser lens at the front of the lamp. These lenses in front of the light bulb distribute the light evenly across the front of the vehicle, and can give a larger range of visibility for the driver. The bulbs themselves are usually common Halogen bulbs that can easily be changed.

For the most part, no. The stock replacement headlight assemblies are a direct equivalent to what is being taken out of the car. You can reuse your old bulbs and sockets, which should fit right in with no modifications needed. Some of the aftermarket units do use different Halogen bulbs than the stock ones. In those cases, we sell the requisite bulb, and really, with the great deal we have on PERDE light bulbs, you can't go wrong with fresh, new bulbs.

Replacing stock Halogen headlights with HIDs would require some modifications, especially where the wiring is concerned. While the lamp can sometimes fit into the opening on the front of the vehicle, your stock lamps will use different bulbs, sockets, fuses, relays, and wiring than most HID bulbs. You may want to check with your local mechanic for advice if you have never attempted this type of conversion before.
