Installation reference images
Before you begin
- Vehicle/product: 2016-2021 Honda Civic 10th Gen LED Quad Projector Headlights.
- SKU check: Confirm your kit SKU or variant matches H-CIV10-CW, H-CIV10-RGB, H-CIV10-RP before removing original parts.
- Reference-first workflow: Review the installation reference images on this page before removing trim or connecting wiring. This guide includes confirmed details from the available reference text and images.
- Power and safety: Switch the vehicle off before unplugging connectors. Disconnect the negative battery terminal when handling wiring, fuse taps, or exposed circuits.
- Protect the vehicle: Use clean towels or masking tape around painted panels and trim edges. Do not force clips or pry against painted surfaces.
- No connector grease: Do not apply dielectric grease or weather-sealing grease to connectors or sockets.
- Headlight note: Keep bumper and liner hardware organized by position, and leave access open until the beam and DRL tests pass.
Reference image checkpoints
- Connector layout: Compare the vehicle connector count, pin count, and adapter harness shown in the reference images before plugging in the RIGNOX headlight.
- Trim level differences: If the reference images show low, mid, high, halogen, LED, or ACC differences, match the page that corresponds to your vehicle before powering the lamp.
- Harness routing: Route DRL, turn-signal, decoder, fuse-tap, or adapter harnesses exactly along the path shown. Keep wiring away from sharp bumper brackets, radiator support edges, and hot components.
- Beam adjustment: Identify the vertical and horizontal adjusters before the bumper is fully reinstalled so beam aim can be corrected after testing.
- RGB/app variants: Confirm controller power, pairing, mode change, and local road-lighting use before final trim reassembly.
Confirmed reference details
- Function points: The reference identifies DRL, turn signal, low beam, high beam, and daylight/turn-signal plug locations.
- Variant difference: The RGB reference adds RGB daylight and app-controlled lighting. Confirm the installed variant before testing RGB functions.
- Beam adjustment: The reference marks up/down and left/right adjusters for high and low beams.
- Low-beam wire: The low-beam wire is called out in the reference. Confirm its routing before the lamp is fully mounted.
- Main plug: The high/low beam and turn-signal plug is shown as the main lighting connector. Confirm the lock tab is seated before bumper reassembly.
Tools and supplies
- Trim removal tool or panel clip tool
- Metric socket and ratchet set; confirm the exact socket sizes against the reference images before removal
- Phillips and flat screwdrivers
- Clean microfiber towels and masking tape for painted bumper and fender edges
- Electrical tape and zip ties for securing included harnesses only
- A wall or flat vertical surface for beam-pattern checking after installation
- A helper for brake, turn, high-beam, and low-beam testing
Remove the original headlights
-
Open the hood and remove the upper plastic cover: Open the vehicle hood and remove the screws securing the plastic protection cover above the front grille area.Carefully remove the plastic cover to access the front-end mounting points.
-
Remove the fender liner screws: Remove the screws located on both sides of the front fender area. Keep all screws organized for reinstallation.
-
Remove the headlight upper trim pieces: Remove the metal decorative trim pieces located above both headlights. Store the trim pieces safely for later reinstallation.
-
Remove the lower bumper screws: Remove the screws and fasteners located underneath the front bumper. Make sure all lower mounting points are released before removing the bumper cover.
-
Remove the front bumper assembly: Carefully remove the entire front bumper cover. Support the bumper during removal to prevent scratches or damage to connected wiring.
-
Remove the factory headlight mounting screws: Remove the five screws securing each original headlight assembly and keep them organized by their original mounting locations. Do not mix the screws, as different positions may require different hardware.
-
Disconnect the headlight wiring and remove the original headlight: Disconnect the wiring connector located on the back of the headlight assembly. Press the connector lock tab and pull from the connector body, not the wires. Carefully remove the original headlight assembly from the vehicle.
Install the RIGNOX headlights
-
Transfer the plastic mounting base: Remove the plastic mounting base from the original headlight assembly. Install the mounting base onto the new RIGNOX headlight assembly.
-
Connect the vehicle harness and install adapters if required: Connect the factory vehicle connector to the RIGNOX headlight, depending on the vehicle trim level, install the required adapter harness if needed. Make sure all connectors are securely locked before final assembly.
-
Reinstall and test the headlights: Install the RIGNOX headlights into the original mounting locations, reinstall all screws, trims, and bumper components removed during disassembly. Test all lighting functions before completing the installation.
Electrical and beam test
- Test low beams, high beams, DRL, parking/position lights, left and right turn signals, hazards, side markers if equipped, and startup animation if equipped.
- Confirm there is no flicker, warning message, hyperflash, or inactive side.
- If a fuse-tap or ACC harness is shown, confirm it is seated in the correct fuse position and secured before closing the fuse box.
- Check beam aim against a flat wall and adjust vertical/horizontal aimers as needed before final bumper reassembly.
- For RGB/app variants, confirm controller power, app pairing, normal mode, RGB mode, speed/brightness controls, and the mode required for road use.
- After all tests pass, reinstall bumper covers, liners, clips, and trim panels.
Final check
- All connectors are fully seated and locked.
- All included harnesses are secured away from movement, sharp edges, water paths, and heat sources.
- Headlight beams are aimed correctly and both sides sit with even bumper and fender gaps.
- All headlights functions test correctly on both sides with a helper operating the controls.
- No warning lights, hyperflash, flickering, abnormal heat, moisture entry, or loose modules remain after a short function check.
Troubleshooting
- One headlight does not turn on: Recheck the main connector, adapter harness, fuse tap if used, and ground connection shown in the reference images.
- DRL or turn signal does not work: Confirm the DRL/turn harness or ACC connection matches the vehicle trim shown in the reference images.
- Warning, flicker, or hyperflash appears: Recheck any decoder, resistor, or trim-specific adapter before adding universal parts.
- Beam pattern is too high, low, or uneven: Re-seat the lamp, confirm all retainers are tight, then adjust vertical and horizontal aimers.
- RGB/app feature does not respond: Confirm the product variant supports RGB, the controller has power, and the app or remote is paired before closing trim.
