All my Lights are working, L&R turn signals, Brakes, 4 way flashers, Head&tail lights, Parking lights work also. Now here's the question parking & tail are on,,, now I turn on the headlights the parking lights turn off. Bad switch or normal operation?
1967 was the last year for that, Starting in '68 all cars were required to illuminate both head and parking lights together and side marker lights were made mandatory.
