Front parking lights stopped working on 71 RR

Recently for no reason the front parking and side marker lights just stopped working. I checked the fuses and the wiring and all looks good. Any idea of why they would just stop working? Turn signals still work in the front.

How did you check ? With yer eyes or a multimeter ? Did you check grounds ?

Uncouple the center 8 pin connector inside your engine bay. Position 10 (Black w/ Yellow tracer) is the parking light feed. Try powering position 10 on that harness from your + battery terminal. If they light up, could be corrosion at the bulk head connector female position. If they don't light, as previously stated, check your ground at the rad support.
At least that is a start.

What about tail lights? Fronts and rear side markers or just fronts?

Just the fronts. The rears and taillights still work. Headlights work, too.

Well, everything points out to the bulkhead connector as mentioned, ALTHOUGHT as far I recall, both front and rear circuits are spliced onto the same cavity at headlights switch connector. Maybe the one running to bulkhead slipped of the terminal at connector. This last stage is really hard it happens, but…
