2. Package Contents

Upon opening the package, please ensure all components are present and undamaged. The package should contain:

• One (1) Passenger Side Headlight Assembly

Note: Bulbs are not included with these headlight assemblies. Please use your vehicle's existing stock bulbs (HB2 type) for installation.

3. Setup and Installation

The WEELMOTO Headlight Assemblies are designed for a plug-and-play installation. However, some vehicle-specific variations may require minor adjustments. Always ensure the vehicle is turned off and the battery is disconnected before beginning any electrical work.

3.1. Installation Steps

1. Prepare the Vehicle: Remove the front grille. Locate and unbolt the screws, clips, or retainer springs that secure the existing headlight assembly. These fasteners are typically found at the top and bottom of the headlight unit.
2. Remove Old Headlight: Carefully disconnect the electrical wiring harness from the stock headlight and then detach the old headlight assembly from the vehicle.
3. Install New Headlight: Position the new WEELMOTO headlight assembly into the vehicle's headlight opening. Ensure it fits securely in place.
4. Connect Wiring: Reconnect the electrical wiring harness to the new headlight assembly. Verify all connections are secure. Ensure all screws, clips, or retainer springs are properly sealed and tightened.
5. Reassemble: Reinstall the front grille and secure it in place.

3.2. Potential Fitment Considerations

Based on user feedback, some 2014 Toyota Tundra models may require minor modifications for optimal fitment:

• Rear Housing Rib: An extra rib on the new headlight's rear housing might interfere with a vehicle mounting tab. This may require careful trimming of the rib to allow the tab to slide and latch correctly.
• Upper Mounting Hole: The upper mounting hole on the new headlight might be slightly undersized. It may need to be drilled slightly larger to accommodate the vehicle's mounting hardware.
• Level Adjuster: If your vehicle has an electronic level adjuster, you can remove it from your old headlight and swap it onto the new assembly. A mounting screw boss on the new headlight might need to be ground down to allow proper seating of the electronic actuator.
• Corner Marker Light: The design of the corner marker light hole may allow the light to spin freely instead of stopping at a fixed point. Ensure it is securely seated to prevent rattling.

Proceed with caution and consult a professional if you are unsure about performing these modifications.

4. Operating and Adjustment

Your WEELMOTO Headlight Assemblies are pre-adjusted at the factory for standard beam patterns. Manual adjustment is generally not required. However, if you observe an unsatisfactory light pattern, you can adjust the beam angle.

4.1. How to Adjust Your Headlights

1. Position Vehicle: Park your vehicle on a level surface approximately 25 feet (7.6 meters) in front of a flat wall.
2. Mark Reference Points: Mark the center points of each headlight on the wall using tape.
3. Isolate Headlights: Block one headlight (e.g., with a towel) to focus on adjusting the other.
4. Locate Adjustment Screws: Open the hood and locate the adjustment screws on top of each bulb housing.
5. Adjust Beam: Turn the adjustment screws as needed until the low beam line is horizontal and the high beam's brightest spot is centered on the 'X' mark you made on the wall.
6. Repeat: Repeat the process for the other headlight.

Caution: Do NOT adjust the regulator more than three times in either a clockwise or counter-clockwise direction to prevent damage to the adjustment mechanism.

5. Maintenance and Care

Proper maintenance ensures the longevity and optimal performance of your WEELMOTO Headlight Assemblies. These headlights are constructed with high-durability materials designed to withstand various environmental conditions.

5.1. Durability Features

• Impact Tested: Designed to pass drop, vibration, rain, ultraviolet radiation, sand, and dust spray tests.
• Temperature Resistant: Engineered for performance in temperatures ranging from -22°F to 140°F.
• UV Coating: Exterior features a UV coating to resist aging and yellowing from sun exposure.
• Waterproof: Designed to prevent moisture ingress.

5.2. Preventing and Addressing Condensation

It is normal for headlight lenses to exhibit temporary misting or fogging due to differences in temperature, air pressure, and other weather conditions. Your headlights are equipped with one-way vents to manage this.

To drive away temporary condensation:

1. Check Vents: Ensure the one-way vents on the headlight housing are not blocked.
2. Activate Lights: Turn on your vehicle's low beams for approximately 20 minutes. The heat generated by the bulbs can help dissipate moisture.
3. Manual Drying (if persistent): If condensation persists, carefully remove the bulbs and clear any visible mist. Placing a silica gel packet inside the housing temporarily can also help absorb moisture.

5.3. Bulb Compatibility Reminder

Safety Reminder: Do NOT directly replace the original halogen bulbs with LED bulbs in these assemblies. These headlights are designed for halogen bulbs, and installing incompatible LED bulbs can lead to improper light patterns, reduced visibility, and potential damage to the headlight unit or vehicle's electrical system.

6. Troubleshooting

This section addresses common issues you might encounter with your headlight assemblies.

6.1. Headlights Not Functioning

• Check Connections: Ensure all electrical connectors are securely plugged into the headlight assembly and the vehicle's wiring harness.
• Inspect Bulbs: Verify that the stock bulbs are correctly installed and not burnt out. Replace if necessary.
• Fuse Check: Consult your vehicle's owner's manual to locate and check the relevant headlight fuses. Replace any blown fuses.
• Vehicle Compatibility: Reconfirm that your vehicle is compatible with these headlight assemblies (refer to Section 1.2).

6.2. Condensation Inside Headlight

As mentioned in Section 5.2, temporary condensation is normal. If it persists or is excessive, follow the steps outlined in "Preventing and Addressing Condensation" in Section 5.2.

6.3. Improper Light Pattern

If the light beam appears misaligned or unsatisfactory, refer to Section 4.1, "How to Adjust Your Headlights," for detailed adjustment procedures.
