Electricity 101: 3rd Brake Light

I've been watching ebay for vintage brake lights, thinking about adding one as a 3rd brake light to my coupe, which has a 6 volt system. But many of the lights for sale are 12 volt.

Knowing very little about the miracle of electricity :o, I wonder whether these 12 volts lights can be made to work with my 6 volt system :confused:.

Does anyone know of a detailed description for boneheads like me of how to convert a 12 volt light to a 6 volt light?

if the 3rd brakelight is using a standard light bulb just put the 6v equivalent bulb in its place.
 
I just used a repo 6v tea cup tail light and mounted it above the spare tire. All I did was splice it into the wiring harness and it works great.

Looks good. The pic is from the Roundup a few years back in Pleasanton. In case you were wondering.
 
Thanks guys. The lights I'm looking at have the standard incandescent bulb, not LED's. So, you're saying all I need is a 6 volt bulb (and maybe a replacement socket if the 6 volt bulb doesn't fit the existing socket). No need to change out the wire pigtail to the light? I think I can handle that.

BTW, Mike: that's a nice set up!

If it has the typical round socket, you should be able to get a 6-volt bulb easy enough. Once you get the bulb out there should be a number on it that will cross to the same bulb only 6-volt.
