It is normal that when u turn on the lights, the front parking lights go out, not a wiring problem at all. i think Ford did that up untill 69, I'd have to look at my friends '69 again.

They should turn on only with the parking lights are on, then go off when u turn on the head lights. Plus they should have the normal blinking. It's kinda a parking light vs running light thing. They were only made for parking lights.
