Hi folks,
I checked the lights in question this morning and they are definitely not parking lights, they are 55w H1 bulbs. So now it makes sense that they would be fog lamps, but my car has the fog lamps in the bumper which come on when the switch is pulled out.

Are these supposed to come on in conjunction with the bumper fog lamps?

Or maybe the headlight assemblies came from a car that did not have fog lights in the bumper, but that would not explain the wiring because it is part of the chassis, not the headlight assemblies.

Any other ideas?

Thank you all for your wisdom,
Matt
