Ususally, what voltage are quarter slot lights?
Ken Layton:
Well, if you're talking about a used coin door, lamp voltage depends on the game it came out of and whether the bulbs were bayonet base or wedge base. Roughly 50% used 6 volt bilbs and 50% used 12 volt bulbs.
Personally I like to use 6 volt bulbs running off of the +5 volt DC from the game power supply. Bulbs last a lot longer that way.

Sorry to dig up this old topic but is the concensus that the regular Happ LED coindoor bulbs are fine with the 5V? Won't be too dim?
Also, I see there's a + and -... don't laugh too hard, but which one gets the ground? I'm assuming negative...?
