Now I have a pair of original tail lights for my 37,not sure if I am going to keep the two bulbs or got with one 1157 in each light. I need to order gaskets and conduit and might be winter before I can get to them since we had nothing but rain I need to do a bunch of other work around the house.
That lens was designed to have two bulbs, one for the running light to shine through the top and the stop light to be lined up with the bulls-eye on the bottom. Putting one bulb (1157) in the center, upper or lower position will diminish the capacity of the other areas and not be as effective in my opinion.

Jeff, If your car is 6 volt you need a 1154 bulb. 12 volt use a 1157 bulb. You do know the bulbs in your current light are single Filament. If you change to a dual Filament 1154/1157 you will have to change the socket accordingly.. Harold
