Re: 01Grand finally gets HIDs and projectors!
Regular halos are LED type bulbs, CCFL's are more brighter, kind of like a neon light. Housings come with the lighting installed already. Try carid.com, you'll see 3-4 different styles there. Some get them from e-bay, some get them from sites like carid.com. You only want HID's for low beams, not high beams.
