Noel, It measure 2"x4" with two bulbs in it. Those tiny 194 bulbs. I went to pwp boys andpicked up two LED bulbs for it too. But those cost me $7. Expensive build lol. I need to cut the end tabs of my frame off but I cant bring myself to do it. Im such a pussy.
Noel:I just did this with a 34 ford repo light.
Noel, Its super easy. The bulbs ground through the mounting screws and the power supplied through a metal strip which is soldered between the two bulb sockets. I just snipped the tiny metal strip and soldered on a second power wire. Wire one bulb to the running light, and the other bulb to the brake circuit. Done.
