taking it off is easy...use a small flathead screwdriver to pry it open...you'll see where it hooks in...its easy as pie. as for the bulbs...they're small wedge bulbs, same ones you would use for your sidemarkers, front signals, license plate lights...i think they're bulb size 194...those are for the map lights. as for the middle dome light...i cant remember the part number...you'll have to pull it out and take it to a local import shop to see if they have it in stock or will get it in stock. my place has them for like 12 bucks for ONE bulb. i can get them for ya for 12 + s&h if you're actually willing to pay that much for them cause i had to get them special ordered.
