Dropped it. Shattered in to a bunch of tiny pieces. Optional bullet light, Suburban/Panel. 3" round. Was changing a bad bulb. Thought I had a spare but I don't. Need it by Saturday. Did an over night order with Chevs of the 40's. They called today and said they have been out of stock for 5 months and no resupply on the horizon. Guess what I did for a small part of my afternoon? Glued the shards together. It'll have to do until I get my own spare supply!
