No, the answer is NOT obvious, so don't feel bad about asking!
I used the following parts from Happ, (although a Radio Shack alternative would work too):
- Mini lamp socket for reflector with metal mounting bracket, part# 91-1224-00
- Mini lamps, part# 91-1219-00
The lamps have two prongs on them. There's no polarity, so it doesn't matter which prong you use as the "hot" and which one you use as the "ground".
I spliced up a power supply from an AT power supply. On a PC power supply red=5v, yellow=12v, and the two blacks=ground. So I spliced up one of the yellow wires and one of the black wires. Viola!
