The Aftermarket kits require cutting the wire harness and mounting the kit on or near the headlight..then run the wires to the bulb socket..Also you will have to seal up the added wires going into the headlight from the kit or water WILL leak into the headlight assy

Also the NON Xenon Headlight housing does NOT have the correct projector OR Cut off light pattern ...

If you are looking to Upgrade the headlights for better night use...The kit is NOT for you

If you want to LOOK Cool then this is what you are looking for
