My A12 Bee's headlights go completely out after they've been on for a while, kick the switch to lows, and they come back on (lows that is) I know that means either the headlight switch, or the dimmer switch is getting hot, or has poor connections. Where is the best place to start?

Start with the headlight grounds on the radiator support. Then check the floor switch for corrosion. Then the only thing left is the headlight switch.

It wouldn't be the headlight switch, because that runs both high and low beams, so it wouldn't matter if you switch to lows when it goes out - they would be out also. I think (but I'm not positive) that the ground would be the same for both high and low beams. If so, then the same thing applies - it wouldn't matter if you switched to low beams, they would still be out.

I'm thinking you have a dimmer switch, or a bad connection, which would most likely be at the dimmer switch, or maybe at the bulkhead connector.

Headlight switch is very likely cause. (my 79 warlock did that after install of 4 hella bulbs. High beams on for a few minutes, went out, clicked back to low beams, came back on. New switch fixed it. I think there is breaker in switch.)

I would check the dimmer switch first. Do a simple feel test. Turn the headlights on high and touch the DS (use back of fingers). If it gets hot, contacts have hi resistance. Power = current squared x resistance. Easiest thing to get to first.

Dimmer switch. Cheap, easy to change. Clean the socket contacts that it plugs into and put dielectric grease in there to protect it from corrosion. It sits in a bad place for moisture.

Can you buy new dimmer switches?

Yep...

Allen Here's a novel idea, let's not throw a bunch of parts at the car hoping it will fix the problem and instead spend a little time diagnosing it first. Life was a little easier when I was just a wrench.

Thx, didn't know that.

Kind of surprised mine is flakey, I have my headlights on relays, so there's not really any current going through the switch or dimmer.

Because the switch is under the carpet and moisture can get to it.

Mopar used the same dimmer switch for several decades. My '68 and '83 trucks use the same thing.

Picked up a dimmer switch at AutoZone, $7.

Replacement is a little taller compared to the original, but it fixed my problem.

Thx!
