I just upgraded all of my lights to LED and didn't test this before. When I run fog lights, then go to brights they shut off as they should. When I go back to dim the fog lights do not come back on. Is this normal function?

 

Normally no.

 

Research and do the "bambi mod". You dont have enough resistance with your current setup.

Perfect! Thank you!
