Try vleds.com they might have what you are looking for. If not putco makes a complete led replacement kit for the map and dome lights.

You can also do a search in the search box. Type in "interior led", it will bring up all kinds of info for ya' BTW, I have the Putco Pure Premium Interior Light Kit and love it. Little pricey though but worth it IMO.
