Had to replace my stereo because it died a couple days ago. Tried last time I installed my stereo to fix it, but couldn't figure out how to pop the button out. Was fiddling with a pocket knife between the top of the button and the bracket.. was about to give up when the thing popped right out. It pulls out (towards the back of the car). There's a small (really small, careful not to lose it) black light socket holder. Get a small screw driver and twist it and the thing pops right off (pull it up and it comes right out). Un-twist the bulb lead wires and yank it out. The replacement slides right in (cut off the excess lead wiring) and wrap it around the holder like the original one was installed (this will probably make more sense when you see it. Install new one and *bam* working light.
