Here goes:just got a new 2019 Silverado 2500hd cab and chassis in at work. Boss bought a new flat bed for me to install. It has 6 led turn/tail lights in back, 4 down low and2 up on the headache rack. Of course it hyper flashes on turn. So I put two resistors - one each on both low lights on the one side I?m trying- still hyper! I add one more resistor to the upper light. Still hyper! I replace all three lights with old incandescent s I had on shelf. Still hyper! So, I have all 3 lights resisted which should slow them down and now bulbs which should never be fast. So what gives? Any Chevy lights guys out there
