Jesus H Christ, don't tell me you did that whole thing with Channellocks.

From your pictures it looked like your drop light has an incandescent bulb. If so, replace it with one of those compact fluorescent Dairy Queen looking bulbs. First and foremost they won't burn you, or anything else, in tight places. Secondly, even rough service bulbs won't take much of a bump to break the filament, usually when it's least convenient. The Dairy Queens will take a lot of abuse.
