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
- Electrical tape and zip ties for securing included harnesses only
- A wall or flat vertical surface for beam-pattern checking
Remove the original headlights
-
Remove the radiator cover clips: Open the hood and use a flathead screwdriver or trim removal tool to release the 19 plastic push clips securing the upper radiator cover.
-
Remove the radiator cover and additional grille clips: Lift the black plastic radiator cover away from the vehicle, then remove the four additional clips located underneath the grille area.
-
Remove the wheel well screws: Working inside the wheel well, remove the three screws along the side and the hidden screw at the upper junction between the bumper and fender. Repeat on the opposite side.
-
Remove the lower bumper fasteners: Reach underneath the front bumper and remove the 10 plastic clips and four screws securing the lower gravel guard to the bumper.
-
Disconnect the main bumper harness: From the driver-side wheel well, reach behind the liner, press the locking tab, and disconnect the large gray electrical connector for the bumper sensors.
-
Remove the front bumper assembly: Carefully pull the sides of the bumper away from their mounting brackets. Gently move the bumper forward until the remaining mounting points release, then remove the complete bumper assembly.
-
Remove the headlight mounting fasteners: Remove the 10mm bolts and push clips securing each headlight assembly. The mounting points include the top, side, and the hidden location behind the lower headlight bracket.
-
Disconnect the headlight harness and transfer the lower bracket: Disconnect the main electrical harness from the factory headlight. Remove the lower black plastic mounting bracket from the factory assembly so it can be reused on the new LED headlight.
Install the RIGNOX headlights
-
Install the new headlights: Install the transferred lower bracket on the new headlight, position the assembly in the original mounting location, and reinstall the mounting fasteners.
-
Test the lighting functions: Connect the main electrical harness, then test the daytime running lights, sequential turn signals, low beams, and high beams before reinstalling the front bumper.
-
Complete the installation and inspect the final fitment: After confirming that all lighting functions operate correctly, reinstall the front bumper, main bumper harness, wheel well screws, lower gravel guard, radiator cover, and all removed clips and fasteners. Confirm that both headlight assemblies are properly seated and review the completed appearance.
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 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.
- Beam pattern is too high or uneven: Recheck lamp seating first, then adjust aim on a flat surface.
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.
