Important: This online guide is a product-side overview for the matched RIGNOX product. It covers what is in the box, how the kit is wired, and what to check before and after fitting. Confirm hidden vehicle-side fasteners, trim clips, and wiring access points on your exact vehicle before removal.
Safety warning: Do NOT use dielectric grease or weather-sealing grease on connectors or sockets. Grease can cause connection problems and may affect warranty coverage.

Product reference images
Reference photography for this kit is being added. Until it appears here, use the image gallery on the product page to compare lamp shape, rear housing, visible plug layout, and lighting functions before final assembly.
Product image checkpoints
- This kit replaces four lamps, not two. The truck carries a headlight and a separate bumper lamp on each side, so lay all four pieces out and identify left from right before anything comes off the truck.
- Match each supplied connector to the corresponding vehicle connector and confirm the lock tab seats fully before reinstalling trim.
- Compare the rear of each new assembly with the original you removed, one piece at a time, rather than removing all four first.
- Do not add universal electrical parts such as resistors or decoders unless RIGNOX support confirms they are needed.
Product notes
- Each headlight uses three projectors: two bi-function projectors for low and high beam, and one dedicated high-beam projector.
- The daytime running light is white. The turn signal sweeps in amber sequence, and a startup animation runs when the ignition is switched on.
- An amber reflector sits at the outer corner of each headlight.
- The kit plugs into the factory connectors; no adapter harness is required.
- 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.
Before you begin
- Confirm the exact product: Check that all four pieces are present and undamaged, and that the lens and housing match the product page images, before removing anything from the truck.
- Confirm your body style: 2007 trucks must be Silverado Classic models. Avalanche owners should confirm the truck does not have factory body cladding.
- Work powered down: Park on level ground, switch the vehicle off, and disconnect the negative battery terminal when handling wiring.
- Work one side at a time: Leaving the opposite side assembled gives you a reference for connector routing and lamp seating.
- Protect body panels: Use clean towels or masking tape near painted edges around the hood, grille, and bumper edge.
- 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 tidying harness routing
- A wall or flat vertical surface for beam-pattern checking
Remove the original lamps
Open the hood and expose the lamp retainers: Locate every retainer for the headlight on the side you are working on before releasing any of them, and note how each one is oriented so it goes back the same way.
Release the headlight assembly: With the retainers clear, draw the headlight straight forward off its locating pins. Do not twist it or lever it against the fender — if it will not come, a retainer is still engaged.
Disconnect the headlight wiring: Support the assembly, release each locking tab, and separate the connectors. Pull on the connector body, never on the wires.
Remove the bumper park / turn lamp: Repeat the same sequence for the lamp below the headlight. Keep the fasteners for each lamp separated, since headlight and bumper lamp hardware is not interchangeable.
Repeat on the opposite side once the first side is fully installed and tested.
Install the RIGNOX lamps
Connect the wiring: Plug the RIGNOX lamp into the factory connectors for that side. No adapter harness is required. Confirm every plug is fully seated and locked.
Test before you close anything up: With the lamp still loose, switch on and confirm low beam, high beam, the white daytime running light, the amber sequential turn signal, and the startup animation. It is far easier to fix a connector now than after the assembly is bolted in.
Seat and secure the headlight: Guide the assembly onto its locating pins, check the gap against the fender and hood, then refit the retainers. The lamp should sit flush without being forced.
Fit the bumper park / turn lamp the same way, then refit any trim you removed.
Repeat on the opposite side, then reconnect the negative battery terminal.
Electrical and function test
- Confirm low beam and high beam operate on both sides, including the dedicated high-beam projector.
- Confirm the white daytime running light, position lamps, amber sequential turn signal, and hazard flash on all four lamps.
- Confirm the startup animation runs when the ignition is switched on.
- Check for dashboard warnings, flicker, or hyperflash before reinstalling final trim.
- Verify beam aim against a flat vertical surface so the cutoff is safe and even.
Final check
- All connectors are locked, dry, and routed without tension.
- All four lamps sit flush with even body gaps and properly seated seals.
- All 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.
- The headlight works but the bumper lamp does not: These are separate assemblies on separate connectors. Confirm the bumper lamp has its own plug fully seated rather than assuming one connector feeds both.
- Warning message, flicker, or hyperflash: Confirm both sides are wired the same way, then contact RIGNOX support before adding any universal load resistor or decoder.
- 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.
Need help?
If the original lamp, vehicle connector, or supplied lamp does not match what you received, stop before modifying wiring. Contact RIGNOX support with your order information, vehicle year/model/trim, and clear photos of the connector area, rear housing, beam output, and installed front-end gap.
