Overview
The Poison Spyder JK LED Tail and Reverse Lights kit, part number 41-08-010, includes what you need to install 4 inch round LED taillights and 2-1/2 inch round LED reverse lights into the Poison Spyder Crusher Corners on a Jeep JK Wrangler. The kit is for the 2-door and 4-door models of the 2007–2018 Wrangler JK.
The harness is designed to connect directly to the Jeep’s factory wiring harness and to the LED taillights, back-up lights and license plate lights that Poison Spyder sells. It is a plug and play answer for getting the JK’s rear LED lighting working quickly.
Key features
- Plug and play connection to the Jeep OE wiring harness
- Two 4 inch round, high intensity 24-LED taillights
- Two 2-1/2 inch round LED reverse lights
- Driver and passenger side wiring harnesses
- Back-up light extension harness
- Built for Poison Spyder Crusher Corners on 2-door and 4-door JKs
Wiring and lighting checks
Rear LED lighting draws little current, but connections in the rear of a Jeep see road spray, mud and temperature swings. Before final assembly, confirm each connector is fully seated and locked, and that the wire routing keeps harness runs away from moving suspension parts, the spare tire carrier and the tailgate hinge.
Test every light before closing up the body. Turn on the tail lights, then shift into reverse to confirm the back-up lights respond. If one side is dim or out, check the ground point and the connector pins before assuming a light has failed. A poor ground is one of the most common causes of intermittent rear lighting.
Sealed connectors and dielectric grease help keep moisture out of the terminals. Route any spare wire into a loom and secure it with clips so it cannot rub through in the trail.
- Test tail and reverse lights before final mounting
- Check grounds when a light flickers or runs dim
- Keep harness runs clear of moving parts and exhaust heat

Vehicle fitment
Based on the product title and description, this kit is for the Jeep Wrangler JK, which covers 2007 through 2018 models with 2-door and 4-door bodies. The harness connects to the JK’s factory wiring, and the lights mount in Poison Spyder Crusher Corners.
The JK is the only generation named, so the kit is not for the TJ, LJ or JL Wrangler. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The harness plugs directly into the Jeep OE wiring harness. The lights mount in Poison Spyder Crusher Corners, so the corners need to be installed before the lights go in.
What’s included
The kit includes two 4 inch 24-LED taillights, two 2-1/2 inch LED reverse lights, driver and passenger side wiring harnesses, and a back-up light extension harness.
Not included: Poison Spyder Crusher Corners and license plate lights, which Poison Spyder sells separately.
