Truck or school bus?

[beejaytx225]

Anyone ever see anything like this? This is with the parking lights on and hazards on. The front parking lights are not coming on. Headlight switch one click out. They were the other day but not now. Left blinker in the rear with lights on just turns the running light on and off. I'm leaning towards headlight switch. Any input?

I'm leaning towards bad grounds .

Make a temporary long jumper wire and hook it to the battery ground and a light base or ground and see if that helps.

I tightened the rear lamp housings, replaced a bulb, replaced both flasher relays and tightened the connector on the bottom of the headlight switch... It all works like a dream now

Cheap and easy.
