I found a kit on ebay a while back for like $40 but you get what you pay for.... Ive replaced every one of them except for the map lights.
Heres a price and bulb list of leds from superbrightleds.com
44mm festoon lmaps = $2.50 per
Used in: 3x each dome light
1x each courtesy light under side mirrors
WLED-xHP miniature wedge base = $5.00 per
Used in: each map light
courtesy lights in doors
glove box
under dash
license plate lamps
Ive used them in all of these places so all together itll cost about $75.00 plus shipping. Also this is for my truck, not sure if you guys with different models have different size or style bulbs. To check em out go to this link.

Dont forget that this price and list is to replace just about every oem bulb inside and out..... not just the domes and map lights like in most of the ebay kits (like the one i originally bought)
