GirlLikeThat - be careful taking the cover off the dome light - it is easy to break off those little tabs that hold it on! If you lean your head back and look up at the lens, you'll see one tab on the side that you push to turn on the light, and two tabs on the other end. Use a small blade (flat head) screw driver and insert it between the lens and light body to release the two tabs, it will then swivel down and the single tab on the other side will come out.
