hmmm does it do it on high beams too or just low ? I would check all connections and the floor high / low beam switch......before i would replace the headlight switch...see if the rear lights flicker too....have someone follow you. and check to see if any other lights are flickering.....

then check the connections at the headlight switch. make sure all the wires are fully pushed into the connector all the way....i had that problem on my starter wire on another car....

 

You probably have a mechanical VR that's worn out. If it was the circuit breaker in the headlight switch the lights would go off and on, not flicker.

 

I have the same thing happening to my headlights. I notice that at some rpms the flickering stops. In my case I believe it has something to do with the petronix electronic ignition that I installed several years ago. All my grounds are good, and like I said, the flickering stops at certain rpms. Its more of a pulsating factor. The lights never go out they just have a noticeable flciker.

 

if they are pulsing u need to upgrade to an electronic voltage regulator if u have the original one just put it in the box to save it for shows etc

i had that problem i traced it back to my dimmer not making good conection

but i also like the solid state regulators i made one for m dash and i got one for my alternator they are since you don't have to set them

 

i was going to say check the floor dimmer switch.

 

It's a grounding problem where you have rust.....
