5. Setup & Installation

These LED bulbs are designed for easy plug-and-play installation. However, always refer to your vehicle's specific service manual for detailed instructions on accessing and replacing bulbs in different locations.

1. **Identify Bulb Location**: Locate the bulb you wish to replace (e.g., dome light, reading light, license plate light).
2. **Access Bulb**: Carefully remove any covers, lenses, or trim panels to gain access to the existing bulb. This may require a small flat-head screwdriver or trim removal tool.
3. **Remove Old Bulb**: Gently pull or twist the old bulb out of its socket.
4. **Insert New LED Bulb**: Insert the new AHLTD T10 COB LED bulb into the socket.
5. **Test Functionality**: Turn on the corresponding light circuit to test if the LED bulb illuminates.
6. **Check Polarity**: If the LED bulb does not light up, remove it, rotate it 180 degrees, and reinsert it. LED bulbs are polarity sensitive and will only work when inserted correctly.
7. **Secure Components**: Once confirmed working, reattach any covers, lenses, or trim panels removed during step 2.

6. Operating Instructions

The AHLTD T10 W5W COB LED bulbs operate in conjunction with your vehicle's existing electrical system. Once installed, they will function automatically when the corresponding light circuit is activated (e.g., opening a car door for dome lights, turning on headlights for parking lights, or engaging reverse gear for reverse lights).

These bulbs are suitable for a wide range of applications:

• Interior Lighting: Dome lights, map lights, reading lights, trunk lights, glove box lights.
• Exterior Lighting: Clearance lights, parking lights, turn signal lights, reverse lights, license plate lights, side marker lights.

7. Maintenance

AHLTD T10 W5W COB LED bulbs are designed for long-lasting performance with minimal maintenance. Follow these guidelines to ensure optimal operation:

• **Cleaning**: If necessary, gently wipe the bulb's surface with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
• **Inspection**: Periodically check the bulbs for any signs of damage or loose connections.
• **Replacement**: Due to their long service life (over 20,000 hours), frequent replacement is not expected. Replace bulbs only if they cease to function.

8. Troubleshooting

If you encounter issues with your AHLTD T10 W5W COB LED bulbs, try the following troubleshooting steps:

• **Bulb Does Not Light Up**:
1. Ensure the vehicle's power is on and the light switch is in the correct position.
2. Remove the LED bulb, rotate it 180 degrees, and reinsert it. LED bulbs are polarity sensitive.
3. Check the bulb's connection in the socket to ensure it is secure.
4. Verify that the vehicle's fuse for that lighting circuit is not blown.
• **Bulb Flickers or Is Dim**:
1. Ensure the vehicle's voltage is within the specified DC 9-16V range.
2. Check for loose connections in the socket or wiring.
3. Some vehicles may require a CANBUS-compatible LED bulb or a load resistor to prevent flickering or error messages, especially for exterior lights. These bulbs are standard and may not include CANBUS functionality.

If these steps do not resolve the issue, please refer to your vehicle's service manual or consult a professional.

9. User Tips

• Before purchasing, always double-check your vehicle's existing bulb type to ensure compatibility with T10 (W5W/194) bulbs.
• Consider replacing all bulbs in a specific lighting area (e.g., all interior dome lights) at once for consistent brightness and color temperature.
• While these bulbs are waterproof, avoid direct high-pressure water spray on exposed bulbs during car washes.
