Supposedly the JScan app can tell the Jeep to change the PWM voltage to constant for LED lights but I am not sure if it covers all years. I am using the Susquehanna box on her 15 JKUR. The first relay I had in my 09 was one that I took off my TJ when I sold it. It worked fine for a few years and then the contacts started sticking. Had to tap it with a wrench to get the headlights to turn off. I replaced it with another cheap ebay relay and the trigger voltage of the new one was higher and I had to add a Truck-lite anti flicker harness to get the relay to turn the headlights on.
