Installation Steps:

1. Prepare the Vehicle: Park the vehicle on a level surface, engage the parking brake, and turn off the engine. Disconnect the negative terminal of the vehicle's battery.
2. Access the Headlight Assembly: Depending on your vehicle model, this may involve removing grille components, bumper covers, or fender liners. Refer to your vehicle's service manual for specific instructions.
3. Remove the Old Headlight: Locate and remove the mounting bolts or clips securing the existing driver side headlight assembly. Carefully disconnect any electrical connectors and vacuum lines (if present). Gently pull the old assembly out of its housing.
4. Inspect and Transfer Components: If your new headlight assembly does not include bulbs or specific wiring harnesses, carefully transfer them from the old assembly to the new one. Ensure all seals and gaskets are in good condition.
5. Install the New Headlight: Position the new Eagle Eyes GM438-B001L headlight assembly into the vehicle's housing. Reconnect all electrical connectors and vacuum lines. Secure the assembly with the mounting bolts or clips removed earlier.

5. Operating Instructions

The Eagle Eyes GM438-B001L headlight assembly operates in conjunction with your vehicle's existing electrical system and controls. No special operating procedures are required for the headlight unit itself.

• Daytime Running Lights (DRL): If your vehicle is equipped with DRLs and the headlight assembly supports them, they will activate automatically according to your vehicle's programming.

Ensure your headlights are always clean and properly aimed for maximum visibility and safety.

6. Maintenance

Regular maintenance helps ensure the longevity and optimal performance of your headlight assembly.

• Cleaning: Clean the headlight lens regularly with a soft cloth and mild automotive soap and water. Avoid abrasive cleaners or harsh chemicals, as these can damage the lens coating.
• Inspection: Periodically inspect the headlight assembly for any signs of damage, cracks, or moisture intrusion. Check electrical connections for corrosion or looseness.
• Bulb Replacement: If a bulb within the assembly fails (if applicable, as some assemblies come with integrated LEDs), refer to your vehicle's service manual for specific bulb replacement procedures. Always use the correct bulb type and wattage.
• Alignment Check: Have your headlight alignment checked periodically, especially after any front-end work or if you notice changes in beam pattern.

7. Troubleshooting

If you experience issues with your headlight assembly, consider the following common troubleshooting steps:

• Headlight Not Working:
  • Check the vehicle's fuse box for a blown headlight fuse.
  • Ensure all electrical connectors to the headlight assembly are securely plugged in.
  • If using replaceable bulbs, check if the bulb is burnt out and replace if necessary.
• Dim or Flickering Headlight:
  • Inspect electrical connections for corrosion or loose wiring.
  • Check the vehicle's charging system and battery voltage.
  • If using replaceable bulbs, the bulb may be nearing the end of its life.
• Moisture Inside Headlight:
  • Small amounts of condensation can be normal and should dissipate.
  • If significant water accumulation or persistent condensation occurs, check for cracks in the housing or improper sealing. Ensure all caps and covers are securely in place.
• Improper Beam Pattern/Alignment:
  • Verify the headlight assembly is securely mounted and not loose.
  • Perform a headlight alignment procedure as described in your vehicle's service manual or consult a professional.
