Does anyone know(I am sure they do) if you replace the entire assy. on the factory driving lights or just the bulb. on an 86 T/A. I think they are driving light because when you just click the parking light switch they energize and they are clear but I am not sure if they were called fog lights or driving lights or running lights back then. My Haynes manual doesn't address any of those.

 

Do you mean these?



Those are driving lamps, sometimes call fog lamps, and have a separate bulb on an '86. Mine does.

 

those are them,thanks so much.
