2. Installation Guide

Before installation, ensure your vehicle's engine is off and the headlights are cool. Always handle the LED bulbs by their base to avoid touching the LED chips.

General Installation Steps:

1. Remove Halogen Bulb: Carefully remove the existing halogen headlight bulb from its housing.
2. Remove Retainer (if applicable): For certain bulb types (H1/H3/H4/H7/H13/9004/9007), you may need to remove the retainer from the LED bulb first.
3. Insert LED Bulb: Insert the LED bulb into the headlight assembly. Ensure it is seated correctly. For H8/H9/H11/H15/H16/9005/9006/9012/5202/880/881/D1/D2 types, insert the LED into the right slot and then rotate to fix it.
4. Secure Retainer (if applicable): If you removed the retainer, re-insert and fix it to secure the LED bulb.
5. Connect Power: Connect the LED bulb's power plug to your vehicle's headlight harness.
6. Adjust Beam Pattern: Rotate the LED bulb to achieve the optimal beam pattern. The S4 Ultra features a 360° adjustable base for precise alignment.
7. Replace Dust Cover: Reinstall the headlight dust cover.

The LED bulb base can be rotated 360 degrees to fine-tune the beam pattern for optimal light distribution.

Dimensions for different socket types to ensure proper fitment.

Achieve a clear cut-off line for low beam and a focused high beam by adjusting the bulb's orientation.

3. Operating Instructions

The NAOEVO S4 Ultra LED Headlight offers multiple lighting modes to adapt to various driving conditions. The color temperature can be changed by cycling your vehicle's headlight switch (turning it off and on quickly).

Lighting Modes:

• 6500K (Sunny Day Mode): Bright white light for clear visibility in normal conditions.
• 4300K (Rainy and Foggy Day Mode): Warm white light, offering better penetration in rain or light fog.
• 3000K (Hazy Day Mode): Yellow light, ideal for heavy fog or hazy conditions to reduce glare and improve visibility.
• Flashing Mode (Emergency Mode): For emergency situations or to attract attention.

4. Maintenance

The NAOEVO S4 Ultra LED Headlights are designed for durability and minimal maintenance. Follow these guidelines to ensure their longevity:

• Regular Inspection: Periodically check the headlights for any debris or dirt accumulation on the lens. Clean with a soft, damp cloth if necessary.
• Avoid Harsh Chemicals: Do not use abrasive cleaners or solvents on the headlight lens or housing, as this can damage the materials.
• Wiring Check: Ensure all wiring connections remain secure and free from corrosion.
• Waterproof Design: The IP68 waterproof rating protects the bulbs from water and dust ingress. However, avoid direct high-pressure water jets on the bulb itself during car washes.

The IP68 waterproof rating ensures the headlights are protected against water and dust, making them suitable for all weather conditions.

5. Troubleshooting

The NAOEVO S4 Ultra LED Headlights are equipped with a smart CANBUS driver to prevent common issues. If you encounter any problems, consider the following:

• Headlight Flickering or Error Messages: The built-in CANBUS driver is designed to prevent these issues in 98% of vehicles. If flickering or error messages occur, double-check all connections. In rare cases, an additional CANBUS decoder might be required for highly sensitive vehicle systems.
• One Bulb Not Lighting Up: Check the power connection to the non-functional bulb. Ensure the connector is fully seated and secure. Test the bulb in the other headlight socket if possible to rule out a vehicle wiring issue.
• Improper Beam Pattern: Re-adjust the 360° rotatable base of the LED bulb until the desired beam pattern (clear cut-off for low beam, focused for high beam) is achieved.
• Radio Interference: The integrated CANBUS driver is designed to be radio interference-free. If you experience interference, ensure the bulb and driver are properly grounded and away from sensitive radio components.

The integrated CANBUS driver helps prevent common headlight errors and radio interference.

7. User Tips

• Optimal Color Use: For best visibility, use the 6500K white light for clear nights, switch to 4300K warm white for light rain or mist, and utilize the 3000K yellow light for heavy fog or snow.
• Beam Adjustment: Take the time to properly adjust the beam pattern after installation. A correctly aimed headlight prevents blinding oncoming drivers and maximizes your visibility.
• Pre-Installation Check: Before fully installing, connect the bulbs to your vehicle's harness and test all lighting modes to ensure they function correctly.
