Parking light help

[c10ss69]

My park lights work when my switch is in the park light position but go out when the headlights are on. Is this normal?

my 67 is the same wondered myself must be normal

Judging by your name you have a 69 and if so then no yours should stay on with the headlights. I have a 69 and mine stay on. If I'm correct only 67 has it where the park lamps turn off when the headlights are on.

My truck is a 69 but I have a painless wiring harness, aftermarket headlight switch (Advance auto parts) and I have a 68 front end on it. Would it be something in the switch or in the harness that makes the parking lights go out when the lights are on? I want them to stay on. Thanks for your help.

Pretty sure it would only be the switch. Inside the switch the contact point for the park lamps are probably shorter in length like the older model year trucks so when its pulled out all the way the go back off.

I found a thread that's some help as well.

Awesome tip! That's the same harness I have so this will fix mine right up. Thanks.
