the harness, relays, and wiring was a kit by matrix/or summit. plugs into the headlight contector to trigger on/off. the H4's are nice and bright and have a selection of different light avalible. like halogen tints, xenon , high pressure sodium.
for the enclosures, i thought Sirius had the best polished, clear projector, all metal H4 housings. nice heavy duty retaining clip an fine rubber boot.
-you still have to tremove the unit to replace a headlight.
