2. Safety Information
Always prioritize safety when working on your vehicle. Failure to follow these safety guidelines may result in injury or damage to the vehicle.
- Ensure the vehicle is parked on a level surface with the parking brake engaged.
- Turn off the engine and disconnect the negative terminal of the battery before starting any electrical work.
- Wear appropriate personal protective equipment, including safety glasses and gloves.
- If you are unsure about any step, consult a qualified automotive technician.
3. Installation Instructions
The ADCARLIGHTS Headlight Assembly is designed for a direct, plug-and-play installation, requiring no modifications to your vehicle's existing wiring or structure. This package includes both passenger and driver side headlight assemblies.
3.1. Tools Required
- Socket wrench set (10mm and 8mm sockets may be needed)
- Flathead screwdriver (for prying clips, if necessary)
- Gloves
3.2. Removal of Existing Headlight Assembly
- Open the hood of your vehicle.
- Locate the bolts securing the existing headlight assembly. Typically, there are two bolts visible from the front and one hidden bolt near the amber lens. For some 2003 Ram Diesel 2500 models, the front bolts may be 10mm and the hidden bolt 8mm.
- Carefully remove all securing bolts.
- Gently pull the headlight assembly forward to disengage any clips or alignment pins. Be aware of any plastic extrusions on the back side of the assembly. If a plastic insert is present in the vehicle body's square hole, and also on the new assembly, one must be removed for proper fitment. It is often easier to remove the attachment from the new light assembly.
- Disconnect all electrical connectors from the bulbs and the main harness.
- Remove the old headlight assembly from the vehicle.
3.3. Installation of New Headlight Assembly
- Connect the electrical harnesses to the new ADCARLIGHTS Headlight Assembly. Ensure all connections are secure.
- Align the new headlight assembly with the mounting points in the vehicle. Carefully push it into place, ensuring all clips and alignment pins engage correctly.
- Reinstall the securing bolts. Do not overtighten.
- Reconnect the negative battery terminal.
- Test all lighting functions (low beam, high beam, turn signals, parking lights) to ensure they are working correctly.

4.2. Headlight Adjustment
Proper headlight aim is crucial for visibility and to avoid blinding oncoming drivers. Your headlight assembly includes adjusters for precise beam alignment.
- Locate the adjustment screws on the rear of the headlight assembly. These typically allow for vertical and horizontal beam adjustments.
- Park your vehicle on a level surface facing a wall approximately 25 feet away.
- Turn on your headlights (low beam).
- Use the adjustment screws to align the beam pattern according to local regulations and vehicle manufacturer specifications. Consult your vehicle's owner's manual for specific aiming procedures.

5. Maintenance
To ensure the longevity and optimal performance of your ADCARLIGHTS Headlight Assembly, follow these maintenance guidelines:
- Cleaning: Regularly clean the outer lens with a soft cloth and mild automotive soap. Avoid abrasive cleaners or harsh chemicals that can damage the polycarbonate lens or UV coating.
- Inspection: Periodically inspect the headlight assembly for any signs of damage, cracks, or moisture intrusion. The assembly is IP65 certified for dust and water resistance, but extreme conditions or physical damage can compromise its seal.
- Bulb Replacement: If a bulb burns out, replace it with the correct type (HB5 for high/low beam, 3157A for turn signal) to maintain proper illumination and electrical compatibility.

6. Troubleshooting
This section addresses common issues you might encounter with your headlight assembly.
| Problem | Possible Cause | Solution |
|---|---|---|
| Headlight not working | Blown bulb, loose electrical connection, faulty fuse | Check and replace bulb, ensure connections are secure, inspect vehicle's fuse box. |
| Dim or flickering light | Poor electrical connection, failing bulb, insufficient power supply | Verify connections, replace bulb, check vehicle's charging system. |
| Moisture inside the lens | Condensation (normal in some conditions), compromised seal | Small amounts of condensation usually dissipate. If persistent or excessive, inspect for cracks or damage to the housing seal. |
| Difficulty with fitment during installation | Misalignment, interference from plastic inserts | Ensure all mounting points are correctly aligned. If plastic inserts on the assembly interfere with vehicle body inserts, remove the insert from the new headlight assembly. |
