Wiring in a set of LED backup lights in a Jeep Wrangler TJ bumper.

Nope. It is my understanding that the resistors are for blinkers. LEDs don’t create enough resistance to activate the blinkers circuit properly. That is why they blink really fast when swapped out for incandescent bulbs. These reverse LED lights just tap into the existing reverse light circuit and just use the power from there to illuminate. FYI they’re still working perfectly on my Jeep today. Go Eagles!

No need for a resister ?
