I also have an electronic LED compatible flasher/ turn signal relay but the reason I used a load resistor in the front marker lights was so the brake lights would work with LED switchbacks in the front turn signals. The 3rd brake light still worked but not the main ones. I think it had to do with the fact that the brake lights are tied into the rear marker lights which are also LED on mine. Maybe not enough load in the marker light circuit.
I think maybe my truck is just too old to have those problems...
Hrmm... now that I have the new lights in the front, I need to wait for a foggy night again so I can update my signature image again!
