Xenon is an inert gas that allows a bulb to produce a brighter light with a longer life than a standard halogen bulb.

Halo lights are lights arranged in a ring around the headlights themselves. You've probably seen them on some cars, such as BMWs, where they are the factory option. In some cases the effect is achieved with bulbs, while on other vehicles it's done with fiber optics. Halo Lights can be a popular upgrade to make your car or truck stand out at night. Please be aware that most of theHalo lights we sell typically have to be manually wired up to your existing wiring harness. This is because your stock vehicle did not have Halos, and there is no wiring pigtail for them on the factory harness.

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.
