it doesn't take bulbs.... it has about 6 leds....i tore one apart and replace one of the leds for practice...my buddy has a soldering kit and he was teaching me. it turned out pretty good but the reason i haven't swaped it is because when you heat to take of the front to get to the leds you end up disfiguring the edges... it takes 4 pin leds and the only place i fount them so far is at radio shack and their $3 a piece....
