Hi Fellas, I have swapped out every bulb to leds. Most everything still works. I got 2 electronic flashers to replace the stock round canister ones. For some reason though... my front corner marker blinkers don't come on at all. The rear flashers just stay on solid and don't blink. I was wondering what exactly the little white box relay is for next to the flasher canister behind the panel? Does that need to be swapped out as well? Thanks so much for any and all help!
