I use the putco leds conversion kit. The reason being is because of the built in fan on the bukbs, that keep them cool. The hids put off a lot of heat and eventually will melt your housing. All I had to do to hook up the leds were trim the outer bezel on the back of the low beam housing. Not much. The leds bulbs are a bit bigger, but they're worth it. I had many hid kits and not one kit lasted longer than 6 months l.
