Default Driving Lights

My driving lights have never worked since I bought my bird. I thought it was the lights themselves but when I applied external power to them, they both worked. So now I'm trying to figure out the circuit. Before I begin pulling my hair out, does anyone have knowledge of how these are powered? My switch is on the panel near the shifter buttons but I have a partial schematic that implies the source is from the Left Rear load center through the "toe board solenoid". Does anyone know what that is and how to get to it?

Default Driving LIghts


Your headlights need to be on high beam in order for the driving lights to operate. There are micro switches on the swingdown assembly that may not be activating properly. Our lights would not work when we got the coach. I replaced one of the switches and they worked for a while. Currently they are not working & I haven't spent any time looking for the problem.

BTW the switch that I subsituted was not an exact match with the original.

The the Bosh relays for the headlights & driving lights are forward of the brake pedal. But only accessible from the panel behind the grill and above the driver headlight.

Correct, by law Driving lights are on with the high beams and Fog lights are on with low beams.

Dave, do your lights swing down and then not work or do they not swing down like mine.
