Weird Lighting Phenomenon - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have noticed that when I have my headlights or parking lights on, my rear lights do not have indication of stopping or turning (signal). When no lights are on (parking or headlights), they work fine. This was the case before I rewired the entire truck with the painless harness for 67-72 trucks, and has not changed even with the LED tails. Is there an assembly that needs to be adjusted under the dash? Just curious.

Everything else works the way they should.
1972 Chevy C10.

Thanks in advance.
