Essential Maintenance Tips for Koito Headlights
Regular Maintenance: Proper maintenance not only extends the life of your headlights but also ensures optimal performance and safety during night driving.
- Regular Cleaning: Remove dirt and debris using a soft cloth and mild soap. Avoid harsh chemicals or abrasive materials that could damage the lens surface.
- Bulb Inspection: Check for signs of damage, wear, or reduced brightness. Replace damaged bulbs immediately to maintain optimal visibility.
- Alignment Check: Ensure headlights are properly aligned to provide maximum visibility without creating hazardous glare for oncoming traffic.
- Brightness Monitoring: Replace bulbs when brightness diminishes, especially with halogen types which naturally lose luminosity over time.
- Wattage Compatibility: When replacing bulbs, never exceed manufacturer's recommended wattage to prevent damage to the electrical system or headlight housing.
- Lens Restoration: Address cloudy or yellowed lenses with a restoration kit or professional service to maintain optimal light output.
Warning: Never touch the glass portion of halogen or HID bulbs with bare hands. Skin oils can create hot spots that significantly reduce bulb lifespan. Always use gloves or handle bulbs with a clean cloth.

- Power Off: Ensure headlights are switched off and consider disconnecting the vehicle battery for safety.
- Access Headlights: Open the hood and secure it properly with the support rod.
- Locate the Headlight Assembly: Identify which headlight needs replacement.
- Remove Protection: Carefully pull out the rubber cover tabs to access the bulb housing.
- Disconnect the Old Bulb: Twist the bulb socket counterclockwise to loosen and remove it.
- Remove Old Bulb: Gently pull the old bulb from its socket. Use gloves or a clean cloth.
- Insert New Bulb: Place the new Koito bulb into the socket, ensuring it's firmly seated.
- Reinstall Socket: Insert the bulb socket back into the headlight assembly and secure by turning clockwise.
- Replace Cover: Reattach the rubber cover, ensuring a proper seal to prevent moisture intrusion.
- Test Function: Turn on the headlights to verify proper operation before completing the job.
Professional Installation Recommendation: For complex headlight systems, particularly full assembly replacements or advanced LED/HID conversions, consider professional installation from a certified technician or Koito-approved service center. This ensures proper fitment, electrical connections, and beam alignment.
