I remember having a droplight with alligator clips, and a 12 volt bulb (the 1960's?)
Here we now have a 12volt LED bulb for $4 with free shipping.

Would that make a nice worklight you could hook to the battery, or is it obsolete now that we have a long lasting LED flashlight?
Flashlight batteries are almost a buck a piece!
