AlphaRex 14-21 Toyota Tundra NOVA-Series LED Proj Headlights Blk w/Actv Light & Seq. Sig + DRL

The AlphaRex 880833 NOVA-Series LED Projector Headlights replace the stock halogen or projector assemblies on 2014-2021 Toyota Tundra trucks with a factory-fit, plug-and-play LED upgrade that delivers dramatically improved road illumination, a modern sequential DRL lighting show, and a blacked-out housing finish that transforms the Tundra's front end. The 880833 uses AlphaRex's patented Ice Cube 3D LED projectors loaded with Osram Oslon Black Flat LED chips for a razor-sharp 6000K output and a perfectly shaped SAE and DOT FMVSS108-compliant cutoff line. All four projectors activate for low beam, and the center LED powers a dedicated high beam, giving Tundra drivers the same technology found in luxury OEM assemblies without any modifications to the vehicle.

Beyond raw output, the AlphaRex 880833 integrates a sequential turn signal tube, a white LED daytime running light tube that wraps the projector housing, and the signature AlphaRex activation light show that fires when the vehicle is unlocked. The polycarbonate lens is coated against fogging, yellowing, and UV oxidation for long-term clarity. The 880833 ships with an adjuster module and a DRL wiring harness for direct installation. Tundra trims with factory-stock LED headlights require the optional extra harness selected at purchase. The assembly is ISO-9001 and ISO-9002 certified and backed by a 2-year manufacturer warranty against defects in materials and workmanship.

Key Features

• Patented Ice Cube 3D LED Projectors: AlphaRex's proprietary projector design with Osram Oslon Black Flat LED chips produces a 6000K output and a clean, regulated cutoff line for oncoming traffic safety.
• Quad-Projector Low Beam: All four projectors illuminate simultaneously for maximum low-beam road coverage, with a dedicated center LED for high beam.
• Sequential Amber Turn Signal Tube: LED light tube sweeps outward in a sequential animation for high visibility turn signals that are visible from further distances than stock incandescent lamps.
• Activation Light Signature Show: When the vehicle is unlocked or started, the 880833 runs through a signature lighting sequence that distinguishes your Tundra from every other truck on the road.
• White LED DRL Tube: Daytime running light wraps around the projector housing for a modern halo-style appearance in daylight.
• Plug-and-Play Fitment: Designed to the exact OEM housing dimensions of the 2014-2021 Tundra for direct bolt-in installation with no drilling or cutting required.
• Anti-Fog, Anti-Yellowing Polycarbonate Lens: Factory-spec hard-coated lens resists UV degradation, road grime fogging, and long-term oxidation.
• SAE and DOT FMVSS108 Compliant: Fully street-legal across all 50 states, ISO-9001 and ISO-9002 certified for quality assurance.
• Blacked-Out Housing Finish: Aggressive matte black housing gives the Tundra a purpose-built, sport truck appearance that pairs well with lifted builds, leveled trucks, and aftermarket bumpers.

Installation Instructions

These headlights are a direct plug-and-play replacement. Professional installation is recommended. If you have experience with automotive electrical work and basic hand tools, a DIY install is achievable in approximately 1 to 2 hours.

Tools Required: 1/4 inch ratchet, 1/4 inch extension, 10mm socket, Phillips screwdriver, flat screwdriver, metal panel clip popper tool.

Important Notes Before You Start:
Do not use dielectric grease or any weather-sealing grease on any connectors or sockets. Doing so will cause connection problems and void the warranty. If your Tundra came from the factory with stock LED headlights, you must select the optional DRL harness add-on before installation. Tundras with factory halogen or projector headlights use the included harness without modification.

Step 1: Pop the hood and disconnect the negative battery terminal before working on any electrical components.

Step 2: Remove the factory headlight assembly. On the 2014-2021 Tundra, the headlight is secured by bolts accessible from within the engine bay and from below the headlight bucket. Use the 10mm socket to remove all mounting bolts (typically 3 to 4 per side).

Step 3: Disconnect the factory wiring harness connectors from the back of the stock headlight assembly. Note the connector positions before unplugging.

Step 4: Connect the AlphaRex DRL harness to the vehicle's factory harness connector. The harness routes the DRL activation signal. For trucks with stock LED headlights, connect the additional harness sold separately before this step.

Step 5: Plug the DRL harness into the back of the new AlphaRex 880833 assembly. Connect the main power and signal connectors as well. Each connector is keyed and will only mate in the correct orientation.

Step 6: Set the 880833 assembly into the headlight bucket and start all mounting bolts by hand before tightening any of them. Confirm the assembly seats flush against the front fascia panel on all edges.

Step 7: Tighten all mounting bolts snugly. Do not overtighten.

Step 8: Reconnect the negative battery terminal, start the vehicle, and test all functions: low beam, high beam, DRL, turn signal, and the activation light show.

Step 9: Aim the headlights. Park 25 feet from a flat wall on level ground. The low-beam cutoff line should be level and even side to side. Adjust the vertical aim screw on the headlight adjuster module clockwise to lower the beam and counterclockwise to raise it.

Step 10: Repeat steps 2 through 9 on the opposite side.

Frequently Asked Questions

Q: Will the AlphaRex 880833 fit my 2018 Toyota Tundra SR5 without any modifications?
A: Yes. The 880833 is a direct bolt-in replacement for all 2014-2021 Tundra SR5 builds. The housing is engineered to the exact OEM headlight bucket dimensions. No drilling, cutting, or bracket fabrication is required. The only consideration is whether your Tundra came with factory LED headlights from the factory, which requires the additional DRL harness add-on.

Q: My 2021 Tundra TRD Pro has factory LED headlights. Do I need anything extra to install the 880833?
A: Yes. Tundra trims that came equipped with factory LED headlights from Toyota require the optional extra DRL harness that can be selected as an add-on at purchase. Without it, the DRL and activation light functions may not operate correctly.

Q: What is the color temperature of the AlphaRex 880833 low beam output?
A: The 880833 uses Osram Oslon Black Flat LED chips calibrated to 6000K, which produces a crisp, pure white light output that is noticeably whiter than factory halogen headlights (typically 3200K) without the harsh blue tint of some aftermarket HID kits.

Q: Does the 880833 have sequential turn signals or just amber LED turn signals?
A: The 880833 includes sequential amber LED turn signals built into the LED light tube around the housing. The turn signal sweeps outward in a wave animation, making your signals visible at much greater distances than static turn signals.

Q: Are the AlphaRex 880833 headlights legal in all 50 states?
A: Yes. The 880833 is SAE and DOT FMVSS108 compliant and certified to ISO-9001 and ISO-9002 quality standards. These headlights are street-legal in all 50 U.S. states.

Q: How long does the AlphaRex 880833 installation take for a DIY installer?
A: For someone with basic automotive tool experience, installation typically takes 1 to 2 hours for both sides. The headlight assemblies are plug-and-play with no wire splicing required. AlphaRex strongly recommends professional installation if you are not comfortable with automotive electrical work.

Q: What warranty does the AlphaRex 880833 come with?
A: AlphaRex provides a 2-year manufacturer warranty against defects in materials and workmanship from the date of purchase. Coverage applies to the original purchaser. The warranty does not cover carrier damage, misuse, modification, normal wear, extreme weather exposure, or solvent damage.

Q: Can I adjust the beam aim on the AlphaRex 880833 after installation?
A: Yes. Each assembly includes an adjuster module. After installation, park your Tundra 25 feet from a flat wall and adjust the vertical aim screw: clockwise to lower the beam, counterclockwise to raise it. Proper aim is critical for your visibility and to avoid blinding oncoming traffic.

Q: Will the AlphaRex 880833 trigger any check engine lights or CANBUS errors on my Tundra?
A: When installed with the correct DRL harness for your specific Tundra trim, the 880833 is designed to work with the Tundra's stock CANBUS system without triggering error codes under normal conditions. Tundras with factory LED headlights must use the additional harness to avoid DRL-related fault codes.

Q: What is the difference between the 880833 Black and the 880832 Alpha-Black version?
A: The 880833 features a standard matte black housing. The 880832 Alpha-Black version uses a deeper, fully blacked-out housing with a darker tint treatment on the lens for a more aggressive blacked-out appearance. Both use identical LED projector technology and feature sets.
