Driving Light Function
« on: May 17, 2018 - 10:11:32 pm »
Can someone tell me how the dring lights on a 71 Cuda are suppose to work.

Mine turn on and only work with the low beams as expected. Now the strange part it that the do not turn off when the head lights turn off. They do turn off when you turn the key off. But if you have the driving lights on, head lights off, and the key off, the running lights are ON. So is it suppose to work that way, you always have to turn the driving Light switch off?

My 71 driving lights are hooked up to keyed ignition - key on and lights are on, IF the switch is on. High beam no lights. whether that is correct or not?? but I think it is.

But if I leave my driving light switch on when the key is off the running lights stay on. Driving lights go off but the  running lights stay on.

Then check to see where the source power comes from. It must be receiving power directly from the battery somehow.

As I recall, the driving lights draw power from the headlight switch or perhaps better said from the dimmer switch in that they are supposed to only work when the low beams are on. However, as they are wired they should come on when the low beams are on and the road lamp switch is on. Get the wiring diagram and check it out. I wired mine on my 73 so that I could turn them on/off independently.
