Default Head Lights Don't Close

I thought I knew everything about the headlight system but here I am ! The headlights open when I turn them on, but they don't close when I turn them off. However, I can open & close them with the over ride switch. Where should I start ?

Look for a broken or disconnected vacuum line. I believe Wilcox has a hose diagram on their web site.

Sounds to me like a problem with the HL switch vac valve.

Thanks guys...The headlight switch was my thought too. I just didn;t want to have to get to it. This is a 79.

This is a long shot that you can try. Pull the blue striped hose off at the pulldown,with the engine running and HL switch pushed in,squirt some silicone or WD into the blue striped hose.Work the HL switch a little.
The silicone should be pulled up and through the HL switch vac valve,if your lucky it will soften the rubber in the vac valve and maybe allow it to seal(if this is the problem).
