I am building a Tamiya sherman (56014 FO) and while installing the light unit, one of the tiny bulbs broke. I talked with Tamiya and they onlly have the entire light unit as a harness for someting in the neighborhood of $40.00, they said just replcae it with one from an electronics store. Great idea, but they didn't know what voltage, plus these lights are ridiculously tiny. I thought they were LED's, but it looks like they have a filament, plus they are made out of glass. If anybody knows where i can get these lights, or has one they want to get rid of, I'll pay. Any help would be great.
