- Mount New Headlights: Carefully position the new headlight assemblies into the vehicle's headlight housing. Secure them using the factory mounting bolts. Do not overtighten.
- Reassemble Vehicle: Reinstall any removed grille, bumper, or trim pieces.
- Reconnect Battery: Reconnect the negative terminal of the vehicle's battery.
- Aiming Adjustment: After installation, it is crucial to properly aim your headlights to ensure optimal visibility and to avoid blinding oncoming traffic. Locate the vertical adjustment screw on the back of the headlight assembly.

Use a Phillips head screwdriver to turn the vertical adjuster. Refer to local regulations or a professional for proper headlight aiming procedures. Do not over adjust the screw, as this can damage the internal mechanism.
6. Operating Instructions
The Xtune projector headlights operate in conjunction with your vehicle's existing headlight controls. No special operating procedures are required beyond standard vehicle operation.
- Turn your vehicle's headlight switch to the "ON" or "AUTO" position to activate the headlights.
- Use your vehicle's high beam/low beam switch as usual. The projector lens design provides a focused beam pattern for improved light distribution.
7. Maintenance
- Cleaning: Clean the headlight lenses regularly with a soft cloth and mild automotive soap or glass cleaner. Avoid abrasive cleaners or harsh chemicals that could damage the lens surface.
- Inspection: Periodically inspect the headlight assemblies for any signs of damage, cracks, or moisture intrusion. Ensure all wiring connections remain secure.
- Bulb Replacement: If a bulb requires replacement, consult your vehicle's service manual for the correct bulb type and replacement procedure. Exercise caution to avoid touching the glass of new bulbs with bare hands, as oils can reduce bulb life.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Headlight not illuminating | Blown fuse, loose connection, faulty bulb, wiring issue. | Check vehicle's fuse box for blown headlight fuses. Verify all electrical connections are secure. Test or replace the bulb. Inspect wiring for damage. |
| Dim or flickering light | Poor electrical connection, low voltage, failing bulb. | Ensure connections are tight and clean. Check vehicle's charging system. Replace bulb if necessary. |
| Moisture inside lens | Condensation (normal in some conditions), seal compromise. | Minor condensation often dissipates. If excessive or persistent, inspect seals for damage. Ensure all caps are securely in place. |
| Improper beam pattern | Incorrect aiming. | Adjust headlight aiming using the vertical adjuster screw (refer to Section 5). |
If troubleshooting steps do not resolve the issue, contact Xtune customer support or a qualified automotive technician.
