I want to replace the bulbs in the rear of my 2016 3500 with LED's. do I have to do as I did with my 2015 Harley Dresser and put in some sort of resister so that they would work correctly?

theyre called load resistors. makes it so your directional don't blink rapidly like a bulb is blown. You can buy them at any auto parts store
