To maintain optimal performance and appearance, regularly clean the headlight unit. Use a soft, damp cloth to wipe down the exterior. Avoid using abrasive cleaners or solvents, as these can damage the lens or casing.
5.2 Battery Replacement
Refer to Section 3.1 for detailed instructions on replacing the AA batteries. Always use fresh, high-quality alkaline batteries for best performance and to prevent leakage.
