You should have a 7443 bulb which is a double filament bulb that controls stop and turn . Have you checked if one of the filaments Broke off? Stop would still work but turn would not if that's the case .
Thanks ! Used vht universal red, and chevy satin black . Vht satin clear to finish it off. Wish I had wrinkle plus but no one locally had it and I couldn't wait for shipping because the leak was getting worse.
Thanks guys. Found one from someone here on the forum for 125 shipped. Surf runner thanks for the pics. Helped alot. I do have tan. Close this mods....
