Product notes

Before you begin
- Confirm the exact product: Compare the RIGNOX headlights 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 hood, grille, bumper edge, or fender liner 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

Remove the original headlights
-
Remove the upper radiator cover: Use a screwdriver or pliers to remove the eight plastic push clips. Lift off the cover.
-
Remove the upper bumper fasteners: Remove the six large bolts along the top of the bumper. Remove one small screw from each side.
-
Release the belly pan: Raise the vehicle safely. Remove the six lower bolts and the push clips on both sides. Leave the belly pan attached to the bumper.
-
Release the wheel well liner: Remove the wheel well clips and pull the liner back. Press the center of each inner retainer and remove it. Use a 10mm socket to remove the two hidden nuts securing the bumper to the fender.
-
Disconnect and remove the front bumper: Disconnect the parking light connector on each side. Lift the bumper off the five upper locating pins. Carefully pull the bumper forward and remove it.
-
Remove the factory headlights: Remove the three headlight bolts. Use a 13mm socket for the side bolt and a 10mm socket for the other two. Disconnect the main wiring connector and remove the headlight.
Install the RIGNOX headlights
-
Connect and secure the Rignox headlights: Connect the factory wiring harness to the Rignox headlight. Place the headlight in the factory position. Reinstall the locating clip and the three mounting bolts. Repeat on the other side.
-
Test the lights and reassemble the vehicle: Turn on the headlights and test all lighting functions. Reinstall the bumper, belly pan, wheel well liners, and upper radiator cover in reverse order.Â
Electrical and function test
- Confirm low beam and high beam operate on both sides.
- Confirm DRL, parking light, amber turn signal, hazard, sequential, and switchback behavior where supported by this product.
- Confirm startup animation or RGB/app functions only after normal road-light functions pass.
- Check for dashboard warnings, flicker, or intermittent operation before reinstalling final trim.
- Verify beam aim after installation so the cutoff is safe and even.
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 headlights 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 may clear as the lamp warms. Heavy or persistent moisture should be documented with photos before continued use.
- Beam pattern is too high or uneven: Recheck lamp seating first, then adjust aim on a flat surface.
- RGB/app feature does not respond: Confirm the product variant supports RGB, the controller has power, and the app/controller pairing has been completed.
