You know those gawdamm little light bulbs that slide into a plastic socket?
Yoters like to use these on the ouside marker lights etc. They are actually quite fragile little connectors. Use pliers and they just pop and then you have to dig the shards out. Nice!
OR...you can squirt some "explosive" brake cleaner in the socket with the dirty stuck little bulb. When it is clean get a piece of the sticky green masking tape and holding it like a clothspin wrap it over the lil bulb. Then you have good traction with your fingers and can jerk the little fawkers out.
