I have the E-code turn signals on the front of my '80 242GT. The top is a white lens, and the bottom is a yellow lens. The turn signal bulb is on the bottom. Both top and bottom lenses light up as parking lights.

To be properly correct, should the top lamp have a yellow or white bulb in it ? Obviously, either would work, and it's a matter of preference, I suppose, but I just was curious as to which way is the way it's designed for.
