Product notes

• Use the product reference images on this page as the product-side visual check for connector layout, rear housing shape, and lighting functions.
• Original vehicle trim, clip style, and fastener locations can vary by year, trim, and previous repairs. Remove panels slowly and verify each fastener before pulling.
• Road-lighting compliance and off-road/show-use notes are product specific. Review the matching RIGNOX product page for the exact language for this item.

Before you begin

• Confirm the exact product: Compare the RIGNOX tail lights to the product reference images, including rear housing, plug layout, lens style, and included modules.
• Work powered down: Park on level ground, switch the vehicle off, and disconnect the negative battery terminal when handling wiring.
• Protect body panels: Use clean towels or masking tape near painted edges around the tailgate, trunk, hatch, bed-side access, or cargo trim area.
• Do not force clips: If a lamp or trim panel does not move, stop and look for another fastener or locating pin.
• No grease on connectors: Do not apply dielectric grease or weather-sealing grease to connectors or sockets.

Tools and supplies

• Trim removal tool or panel clip tool
• Metric socket and ratchet set; verify exact sizes on the vehicle before removal
• Phillips and flat screwdrivers
• Clean microfiber towels and masking tape
• Electrical tape and zip ties for securing included harnesses only
• A helper for brake-light and reverse-light testing

Remove the original tail lights

1. Remove the tail light access cover: Use a plastic trim removal tool to carefully pry off the small black access cover inside the cargo area, exposing the tail light mounting nuts and wiring connector.
   
   
2. Disconnect the harness and remove the mounting nuts: Unplug the factory tail light wiring connector, then use a 10 mm deep socket and ratchet to remove the two mounting nuts located at the top and bottom.
   
   
   
3. Remove the factory tail light: Carefully release the retaining clips along the outer edge of the tail light with a plastic trim removal tool, then pull the assembly straight outward from the vehicle.
   
   

Install the RIGNOX tail lights

1. Install the new LED tail light: Confirm the correct side, route the new tail light harness through the center body opening without pinching the wires, and press the locating pins into the mounting holes.
   
   
2. Reinstall and secure the tail light: Hand-start the two 10 mm mounting nuts and tighten them with a socket, connect the wiring plug until it locks into place, and reinstall the access cover.
   
   
3. Test all lighting functions: Turn on the vehicle power and test the startup animation, brake lights, and sequential turn signals to confirm that the new LED tail lights operate correctly.
   
   

Electrical and function test

1. Confirm running/parking lights on both sides.
2. Confirm brake lights with a helper pressing the brake pedal.
3. Confirm left and right turn signals, hazards, and sequential behavior where supported.
4. Confirm reverse lights with the vehicle safely in reverse and the parking brake applied.
5. Confirm startup animation or RGB/app functions only after normal road-light functions pass.
6. Check for dashboard warnings, hyperflash, flicker, or intermittent operation before reinstalling final trim.

Final check

• All connectors are locked, dry, and routed without tension.
• Included modules or extra harnesses are secured away from heat, water paths, moving parts, and sharp edges.
• Both tail lights sit flush with even body gaps and properly seated seals.
• All supported lighting functions pass on both sides.
• No warning lights, flicker, hyperflash, abnormal heat, moisture issue, or loose wiring remains after a short check drive.

Troubleshooting

• One lamp does not turn on: Recheck the main connector lock, related fuse, and battery connection.
• One function does not work: Compare the plug area to the product reference images and verify the connector is fully seated.
• Warning message, flicker, or hyperflash: Confirm the correct product variant was installed and that any included decoder, resistor, or relay is connected and secured.
• Moisture appears: Light condensation right after installation is normal and usually clears within about a week of regular driving as the lamp warms up. If water collects inside or the moisture doesn't clear, contact RIGNOX support.

Need help?

If the original lamp, vehicle connector, or included harness does not match the product reference images, stop before modifying wiring and contact RIGNOX support with your order number and your vehicle's year, model and trim. We'll walk you through it.
