While driving down the road my headlights cut off on my car, but eventually came back on. I noticed when it started doing that I was not able to use the headlight dimmer switch. It was not clicking any more. So it will not go from high to low or low to high. What could it be?

Hello,

It sounds like it could be a faulty headlight switch. It is possible to have corrosion on the connectors that is triggering the intermittent light on and off.

Check the connectors and make sure it is secured, free of corrosion or burnt pin(s).

Here is a helpful guide:

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
