The Stovebolt Site Forums The Shop Area The Electrical Bay Tail light confusion

With the original two bulb tail light you might have to mount a separate light to use as a turn signal. The problem with your housing is a bright bulb won't fit without bending the bracket the sockets mount to. I use a #81 6cp bulb for my tail light and a #1129 21cp bulb for the brake light. I believe originally a #63 3cp bulb was used for the tail light and the #81 was the brake light. As I mentioned the bracket must be bent some to use the #1129 because it's longer and won't clear the lens. I don't know what the 12v equivalent bulbs would be.
