1968 F250 Headlight Switch

I bought a new headlight switch and high beam switch and when I turn on the headlights the parking lights in the front go out and I don't know why.? When I pull the switch out one notch the parking lights come on but when I pull the switch all the way out the parking lights in the front go out?

that's how it's supposed to be. I think 70 is when they started staying on.

That's the way things worked back then, parking lamps go off when headlamps go on.

The parking lights on my '69 Ranger stay on when I turn the headlights on.



Oh, wait ....that's because I modified it to do that. Never mind.


This can be done on pre-'70 model trucks by simply jumpering out the light switch.




But, would be better if the circuit was run through a relay to reduce some of the electrical load.
