To adjust the headlights, locate the adjuster screw on the rear of the headlight housing. Use an appropriate tool (e.g., Phillips head screwdriver) to turn the screw. Turning the screw will raise or lower the light beam. Perform adjustments on a level surface, facing a wall, and follow local regulations for proper headlight aim.

6. Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your headlight assembly.
UV Protection:
The headlight lenses are treated with a UV coating. This coating provides UV resistance and impact resistance, which is crucial in preventing yellowing or cracking over time due to sun exposure. This helps maintain clear light output and extends the service life of the headlights.
