Installation Instructions
The Nilight Headlight Assembly is designed for direct bolt-on OE fitment, requiring no modification or drilling for installation. It is a plug-and-play replacement for your stock unit.
- Preparation: Ensure your vehicle is turned off and the battery is disconnected before beginning installation.
- Remove Old Headlight: Carefully unbolt and disconnect the wiring from your existing headlight assembly.
- Install New Headlight: Position the new Nilight Headlight Assembly into place. Secure it with the original bolts.
- Connect Wiring: Reconnect the electrical wiring to the new headlight. Ensure all connections are secure.
- Adjust Beam Angle: Use the high/low beam adjuster to set the desired beam angle. This may require fine-tuning after initial installation.
- Test Functionality: Reconnect the battery and test all headlight functions (low beam, high beam, turn signal) to ensure proper operation.

Operating Instructions
Once installed, operate your Nilight Headlight Assembly using your vehicle's standard headlight controls. Ensure proper alignment for optimal road illumination and to avoid dazzling oncoming traffic.
- Low Beams: Use for general driving, especially in urban areas or when following other vehicles.
- High Beams: Activate for maximum illumination on dark roads with no oncoming traffic. Remember to switch to low beams when approaching other vehicles.
- Turn Signals: Use your vehicle's turn signal lever to activate the integrated amber turn signal lights when changing lanes or turning.

This image compares Nilight's optimized Z-shaped beam pattern, which provides wider vision and anti-glare properties, against a narrower, less effective beam pattern from other headlights.

- Cleaning: Clean the headlight lenses regularly with a soft cloth and mild soap solution to remove dirt and debris. Avoid abrasive cleaners that can scratch the lens.
- Inspection: Periodically inspect the headlight assembly for any signs of damage, cracks, or moisture intrusion. Address any issues promptly.
- Bulb Replacement: If a bulb burns out, replace it with the correct type as indicated below.

This diagram illustrates the required bulb types for the Nilight Headlight Assembly: H11 for the low beam, 9005 for the high beam, and 3157NA for the turn signal light. Bulbs are not included with the assembly.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Headlights not working | Blown fuse, faulty bulb, loose wiring connection. | Check vehicle's fuse box, replace bulbs, inspect and secure wiring connections. |
| Dim or flickering lights | Weak electrical connection, aging bulbs, insufficient power supply. | Check wiring for corrosion or looseness, replace bulbs, consult a professional for electrical system check. |
| Moisture inside headlight | Seal compromise, extreme temperature changes (condensation). | Ensure proper installation and sealing. Small amounts of condensation may dissipate naturally. If persistent, inspect for damage or contact support. |
| Improper beam alignment | Incorrect adjustment during installation. | Re-adjust the high/low beam adjusters as needed. Refer to your vehicle's manual for specific alignment procedures. |
