hi , I’m new on this forum. I installed aftermarket fog lights with halogen bulbs. And everything worked good. I Direct wired to go on with lights but when I changed to H-11 LED bulbs , now the automatic light control buzzes until I turn it off. Help!

 

Aftermarket fog lights usually behave fine with halogens, but once LEDs go in, Cadillac accessories often cause fewer electrical quirks because the factory system expects a certain load. The buzzing from the auto‑light control typically means the circuit isn’t seeing enough resistance, so a load resistor or decoder tends to solve the issue.

 

Thank you.
