Yes, it might. Six years in my uncle’s barn.
If it's the old standard 1153 type bulb (round brassorsomemetal sleeve with two bumpy things on the bottom for the 'hot' side and it pushes down into the socket and twists, just pop the bulb out, eyeball down into the socket and see if there's a whitish powdery crud in there. You can scrape that glop off with a pocket knife (after removing any possibility of anyone turning on the light/signal/stomping on brake, although I think the fuse would blow before the knife blade reached incandescence if a voltage source were somehow encountered... ;-) and stick a rag wrapped around a pen/pencil/screwdriver down into the socket to wipe the residue out...
I'd loan you my pocket knife but someone here insists that I have damaged it beyond all resurrection. Of course he says that everytime I have him sharpen it..
