Sorry guys I thought I deleted this post. I was messing with it, one side the bulb popped out of the socket and is rattling around in the housing. The other bulb shattered as I pulled it out. In wondering how the bulbs got in there if they were that big? Or do they expand with use?
Agree with PBR that the bumper doesn't need to come off. If you still want to though, you need to unscrew the front of the light, at e the bulb out (from the front), and then the bulb holder comes out the back. The bulb will not fit out the back.
