I installed them in a Caravn , they have plastic headlight housings , the HID do not seem to make excessive heat & use less power , I do not know of a plug & play kit but it may be available , it is a 5 wire install , you just need a High & low beam trigger from one light socket , the harness comes with plugs for the ballasts & the lights plug inot the ballast & includes a relay to take power from the battery or battery post on the start relay.
