I have a 66. The parking lights work with the switch halfway out. When I pull it all the way out, the parking lights go out. The turn signals work fine. Is my switch bad? If not can I make them work with the lights on?

I'm rewiring my car right now, so I have an idear or two about how to do it. The should be a parking light power wire, as well as a running light power wire on the switch. When the switch is pulled all the way out, the parking light power is disengaged and the running light is engaged. If you run it into the running light power post, you should be successful. I will look more closely at it tomorrow and let you know if I just made a buffoon of myself.

My first car was a 64' Corvair, I too wanted the parking lights to come on with the head lights. I just put a diode between the two wires (at the switch) that powered the head lights and parking lights. If you dont know what a diode does, it only lets power go one way, that way, you still have parking lights in the parking light position and head lights and parking lights in the head light position. It's been so long ago (back in 1975) when I did it, so I really dont remember which wires or what size diode I used, but it worked for me....

Just an idea,,,,,,,,,,,, Good luck..

If you want to run your parking lights all the time, here is a way to do it, very simple.

Thanks for the idea. While I was waiting around today I tested and documented this process for my 66 Chevy II. I added a new thread in the electrical section with the link. Maybe it can be a sticky or put it in the best of electrical since this is asked so often.

Hey there.
So I recently purchased a 65 Nova. Obviously noticed the parking light problem. So I did relocate the purple wire in the connector and it did fix the parking light issue but only in the front. Do I need to add a wire from switch to the rear lamps??

I asked this same question a couple of years ago about my 63. Here is a link to the solution that worked for me on the 63. Quite simple.
