The led and eye are plug and play. The hid you have to treat just like an aftermarket hid install (relay harness resistors ballasts and bulbs). This set came with relays and ballasts but no bulbs. These are aftermarket Chinese headlights and so far the housings are superior quality. Once i get the right bulbs ill be able to check the projector. The sonic crew is working on making these and several others available. The other styles won't be ready until mid Feb.
