Yep. I usually pick up coin door bulbs at Walmart in the auto section. #94's are 12 volt I think. You either have wedge base, or bayonet base. If you put in a 12 volt bulb, you are safe either way. If it is a 12 volt circuit, then you're good. If it's a 5-6 volt circuit, the bulb will be slightly dimmer and last for pretty much ever.
