I know this sounds crazy but I am trying to install new 12V turn signal bulbs on my 1954 Belair and the housing they go in with not lock them into place at all. I can push them into the grooves but the bulb won't turn at all to lock them in. Anyone else with these cars have this issue? How did you get them to lock into place? P.S. I have the locking tabs on the new bulbs going into the housing the right way.
