I've been replacing all my bulbs with LEDs and I discovered on Saturday that I have the dreaded rusty license plate bulb cover screw issue. The heads are still there but my screwdriver chewed them up pretty good, so now I need some sort of screw-out solution to get them out.

Suggestions? Also, does anyone know the thread/pitch/length offhand? I'm thinking of buying stainless steel replacements to keep this from happening again.
