Headlight switch drama

when I pull it out to bring on the headlights, the front parking lights go off while the rear parking lights remain lit. I assume that this is normal

Yes, until Federal Motor Vehicle Safety Standard 108 took effect on 1/1/68, then the parkers had to stay on with the headlamps so oncoming drivers could still see the width of your car after a headlamp burnout at night.

and that maybe the DOT mandated they stay on with the headlights sometime after 1964. Seems like I saw or heard that somewhere.

It was here (or one of the other times I posted it), along with E-Z instructions on how to do the safety upgrade.

(Also, Standard Motor Products bought Echlin, BWD, and Niehoff from Dana in 2003)
