I wanna say it's a 6024 number or something like that. It's a 7" sealed beam. There are 3 flavors of Sylvania. Standard, bright (the one I got) and the silverstar. IT's REALLY simple. Two screws to pop the front of the loght off, then undo the spring thing around the outside to release the lense from the chrome ring, then unplug the bulb, plug in the sealed unit, stick it in the chrome ring and pop the spring retainer back in. Done.
