Installation reference images
Before you begin
- Vehicle: 2023-2026 Honda Accord 11th Gen sedan tail light and trunk-lid light-bar installation.
- Tools confirmed from the reference images: ratchet wrench, 10mm socket, 8mm socket, and pry/trim removal tool.
- Protect the trunk trim: The installation requires removing trunk trim, PE foam, license-plate-opening fasteners, and the original camera from the trunk-lid assembly.
- Low-trim note: The reference shows separate low-trim harness adapters for the cornering lamps and through-light. Confirm whether your vehicle needs the supplied low-trim harness before final assembly.
Remove the original trunk-lid through-light assembly
-
Remove the trunk-lid liner: Use a trim removal tool to release the plastic retaining clips from the inner trunk-lid liner. Remove the liner to access the wiring and mounting fasteners underneath.
-
Disconnect the electrical connectors and harness retainers: Disconnect the rearview-camera connector and main tail light connector. Release the wiring-harness retainers from the trunk lid.
-
Remove the center tail light mounting hardware: Use an 8 mm or 10 mm socket to remove all nuts and screws securing the full-width center tail light assembly. Keep a firm hold on fasteners located inside recessed openings to prevent them from falling into the trunk-lid cavity.
-
Remove the factory center tail light assembly: Apply even outward pressure along the center tail light assembly to release its retaining clips from the mounting slots. Carefully remove the complete assembly from the trunk lid.
-
Remove the factory rearview camera: Press the retaining tabs on both sides of the rearview camera and remove the camera from the back of the factory center tail light assembly. Set the camera aside for installation in the replacement assembly.
Remove the original outer cornering lamps
-
Remove the outer tail light access covers and screws: Use a trim removal tool to carefully pry off the small plastic access cover beside each outer tail light. Remove the two exposed mounting screws.
-
Remove the factory outer tail light assemblies: Disconnect the electrical connector from each outer tail light. Carefully release the retaining clips and pull both outer tail light assemblies away from the vehicle.
Install the RIGNOX through-light and outer lamps
-
Install the Rignox tail light assemblies: Install the factory rearview camera into the replacement center tail light assembly. Connect each Rignox connector to its matching factory connector, including the brake-light connectors and center connection cable.
-
Connect through-light and outer lamps: Route the wiring for the outer tail lights through the openings on both sides of the trunk lid. Position the center and outer tail light assemblies in their factory mounting locations and secure them with the previously removed hardware.
-
Test all tail light functions: Before reinstalling the trunk-lid liner, turn on the vehicle lights and verify the running lights, brake lights, turn signals, reverse lights, and full-width light bar. Reinstall the trunk-lid liner and all plastic retaining clips after confirming proper operation.
Function test before final trim
- Reconnect power temporarily and test running lights, brake lights, turn signals, hazards, reverse lights if applicable, startup animation, and RGB/app control if equipped.
- Confirm the rear camera image works after the camera is transferred and reconnected.
- Open and close the trunk slowly to confirm the routed connecting wire does not stretch, pinch, or rub on the hinge/rocker arm.
- After all functions pass, reinstall the PE foam, trunk clips, license-plate-opening trim, and trunk-lid panels.
Troubleshooting
- Through-light does not sit flush: Recheck the white clips and hold the assembly upward while tightening the screws.
- Camera does not work: Recheck the camera transfer, connector lock, and left-side connector shown in the reference.
- One side does not light: Recheck whether the vehicle needs the low-trim harness adapter or the standard harness connection.
- Wire rubs when the trunk moves: Re-route the flat/curved light connecting wire and secure it with zip ties along the path shown in the reference.
Need help?
