I have replaced all my exterior lights with leds on my 01 Tahoe and they all work except my turn signals when the headlights are on. No hyper flashing. They just only work when headlights are off. I disconnected the headlights but it didn't help. Any similar experiences/thoughts

Can you try flipping the wires?

Welcome to the Forum from NH.

Lots of knowledgeable folks here who freely share their knowledge, experiences, and perspectives. Knowledge is power.

I hope that you will become a participating member in the Forum's discussions.

Pics of the truck, please.

You are already receiving sage advice from the knowledgeable folks on this Forum.

As stated above, check your wires and connectors first to ensure that the connections are correct.

What kind of bulbs did you use? I'm assuming 3157's LED equivalent, but might as well ask.

Do they only work when no other lights are on? Do the headlamps need to be on for them to stop working or does having only the parking lamps on do the same? Does turning the high beams on change anything? Does the instrument panel show that the signal but the bulb doesn't turn on or literally nothing?
