What i did for my domes was went to superillumination.com, bought 2 round 8 led utility lights(utility section), cut out the existing light housing and wired the lights right to the leads, super easy, huge light and not as time consuming as the thread you may have read, he's an led master, i could'nt do that. Fot the license plate, puddle lights, and the rear domes, I just replaced the bulbs with superwhite leds that they offer(alot of diff kinds to choose from) I did'nt do the headlights or tails(they did'nt produce enouph light in the tails to shine thru the red lens) Headlights 4 me I would do an hid conversion. the signal lamps i did replace with leds but u have to get load equalizers and wire them in(easy and cheap) and the look great behind clear side markers(also easy and cheap). good luck
