No running lights

when i turn on the running lights or my headlights only one of the three lights turn on. the turn signal lights work normally with the signal but not with the headlights. i dont know if its in the wiring or a worn out switch.

The signals are a separate filament. Whether they work has no bearing on whether the parking lights work.

It's not the switch. All the parking lights / taillights are fed from the same set of contacts on the switch.

Did you check the small upper side marker light bulbs (IIRC they're 168/194 peanut bulbs)?

Do the taillights work?
