3. Installation Guide
These headlights are designed for direct OEM replacement, meaning no modification to your vehicle is typically needed. However, professional installation is strongly advised to ensure correct fitment, wiring, and beam alignment.
Before Installation:
- Ensure the vehicle is parked on a level surface with the engine off and the parking brake engaged.
- Disconnect the negative terminal of the vehicle's battery.
- Gather necessary tools (e.g., screwdrivers, wrenches, trim removal tools).
Installation Steps (General):
- Remove Old Headlights: Carefully remove any retaining clips, screws, or bolts securing the existing headlight assembly. Disconnect all electrical connectors and carefully pull out the old headlight unit.
- Inspect New Headlights: Before installing, inspect the new AmeriLite headlight assemblies for any visible damage.
- Connect Wiring: Connect the main electrical connector from your vehicle's harness to the new headlight assembly. Ensure all connections are secure. The running light may require connecting separate power and ground wires if not integrated into the main connector.
- Position and Secure: Carefully slide the new headlight assembly into its mounting position. Align the mounting posts and secure the unit using the original retaining clips, screws, or bolts.
- Test Functionality: Reconnect the vehicle's battery. Turn on the vehicle's lights (parking lights, low beams, high beams) to ensure all functions are working correctly.
- Aim Headlights: Proper headlight aiming is critical for safe driving and to avoid blinding oncoming traffic. This step should ideally be performed by a professional using specialized equipment.

4. Operating Instructions
Once installed, the AmeriLite Crystal Headlights operate in conjunction with your vehicle's existing lighting controls. Refer to your vehicle's owner's manual for specific instructions on operating your vehicle's lighting system.
- Low Beams: Provide illumination for general driving conditions, designed not to blind oncoming traffic.
- High Beams: Offer maximum illumination for driving in dark areas without oncoming traffic. Use with caution.
- Running Lights: Provide daytime visibility for your vehicle.
5. Maintenance
Regular maintenance will help ensure the longevity and optimal performance of your headlights.
- Cleaning: Clean the outer lens regularly with a soft cloth and mild automotive soap or glass cleaner. Avoid abrasive cleaners or harsh chemicals that could damage the polycarbonate lens material.
- Inspection: Periodically inspect the headlight assemblies for any signs of damage, cracks, or moisture intrusion. Although the product is waterproof, extreme conditions or impacts can compromise seals.
- Bulb Replacement: If a bulb burns out, replace it with the correct type (H3 for low beam, H4 for high beam, 194 for running light). Refer to your vehicle's manual or a professional for specific bulb replacement procedures.
6. Troubleshooting
If you experience issues with your headlights, consider the following basic troubleshooting steps. For complex issues, professional assistance is recommended.
| Problem | Possible Cause | Solution |

| Headlights not working | Blown fuse, faulty bulb, loose connection, wiring issue | Check vehicle's fuse box. Inspect and replace bulbs. Verify all electrical connections are secure. Consult a professional for wiring diagnostics. |
