I’m working on the front end of a 1948 GMC COE. Someone in the past mounted turn signal lamps on top of the front fenders. They don’t look good at all. And, they’re coming off.

The factory signals are still there, just below the headlights. But, they look very small. I think that they're too small for safety. But, I like the location.

Has anyone found a signal lamp that can be adapted to fit the location of the factory units? I am looking for something that is a bit larger, would match the style of the truck and can be seen from a distance.
