6.5. Headlight Aiming Adjustment
After installation, it is crucial to adjust the headlight aim for optimal visibility and to avoid blinding oncoming drivers. Use the integrated adjuster screw on the back of the headlight assembly (refer to Image 5.2).
- Reconnect the vehicle's battery.
- Park the vehicle on a level surface approximately 25 feet from a wall or garage door.
- Turn on the low beam headlights.
- Use a screwdriver to turn the adjuster screw until the headlight beam is properly aligned according to local regulations or vehicle manufacturer guidelines.
7. Operation
The AXLAHA Headlight Assembly functions identically to your vehicle's original headlights. It provides both high and low beam illumination, as well as turn signal indication.
- Low Beam: Provides general illumination for normal driving conditions.
- High Beam: Offers maximum illumination for driving in dark areas where no oncoming traffic is present.
- Turn Signal: Indicates your intended direction of travel.
Ensure all lighting functions are checked after installation.
8. Maintenance
Proper maintenance will extend the life and performance of your headlight assemblies.
8.1. Cleaning
- Clean the outer lens regularly with a soft cloth and mild automotive soap or glass cleaner.
- Avoid abrasive cleaners or harsh chemicals that could damage the lens or UV coating.
8.2. UV Protection and Durability
The headlight assemblies feature a UV coating designed to resist yellowing and cracking over time, and are constructed to be dustproof and waterproof (IP70 rated).

9. Troubleshooting
If you encounter issues with your new headlight assembly, consider the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Headlight not working | Blown bulb, loose electrical connection, blown fuse | Check and replace bulb, ensure connections are secure, check vehicle's fuse box. |
| Dim or flickering light | Poor electrical connection, faulty bulb, vehicle's charging system issue | Inspect connections, replace bulb, consult a mechanic for charging system diagnosis. |
| Moisture inside lens | Condensation (normal in some conditions), seal compromise | Small amounts of condensation should dissipate. If persistent or excessive, check for proper installation and seal integrity. |
| Improper beam aim | Headlights not adjusted after installation | Refer to Section 6.5 for headlight aiming adjustment. |
If these steps do not resolve the issue, please contact AXLAHA customer support.
