There is a resistor reostat built into the headlight switch. As you turn the knob the lights get brighter/dimmer. Make sure you have it hooked to the correct term. on the switch. They generally use a grey wire & anyone can work that has a good bulb & is hooked up correctly. It's possible the resister in the switch is burned out.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
