5. Installation

Follow these general steps to install your AHLTD T10 COB LED bulbs. Specific procedures may vary slightly depending on your vehicle model and the light fixture you are replacing.

1. **Turn off Vehicle Power:** Ensure your vehicle's ignition is off and the lights are switched off to prevent electrical shock or damage.
2. **Locate the Bulb:** Identify the light fixture where you intend to install the LED bulb (e.g., dome light, trunk light, clearance light).
3. **Remove the Old Bulb:** Carefully remove the cover of the light fixture, if applicable. Gently pull out the existing T10 bulb from its socket.
4. **Insert the New LED Bulb:** Insert the AHLTD T10 COB LED bulb into the socket. T10 bulbs are polarity sensitive. If the LED does not light up, remove it, flip it 180 degrees, and reinsert it.
5. **Test the Light:** Turn on your vehicle's power and test the newly installed LED light to ensure it functions correctly.
6. **Reassemble:** Once confirmed working, replace the light fixture cover.

• **Cleaning:** If necessary, gently wipe the LED bulb's surface with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
• **Inspection:** Periodically check the bulbs for any signs of damage or loose connections.
• **Replacement:** Due to their long lifespan, frequent replacement is not typically required. Replace only if a bulb fails.

8. Troubleshooting

Common Issues and Solutions:

• **Bulb does not light up:**
  • Check the polarity: Remove the bulb, flip it 180 degrees, and reinsert.
  • Ensure the bulb is fully seated in the socket.
  • Verify the vehicle's power is on and the light switch is activated.
  • Check for blown fuses in your vehicle's electrical system.
• **Bulb flickers or is dim:**
  • Ensure the bulb is receiving the correct 12V DC power.
  • Check for loose connections in the socket or wiring.
  • Some vehicles may require a CANBUS decoder to prevent flickering or error messages with LED bulbs (not included).

10. User Tips

• **Polarity Check:** If the LED bulb does not illuminate upon installation, remove it, rotate it 180 degrees, and reinsert it into the socket. T10 LEDs are polarity sensitive.
• **Brightness Concerns:** If the lights appear dim or 'barely shine', ensure the bulb is fully seated in the socket and that your vehicle's electrical system is providing the correct 12V power. Verify there are no loose connections or corrosion in the socket.
• **Compatibility:** While designed for universal T10 sockets, some modern vehicles with complex electrical systems may require additional CANBUS decoders to prevent error messages or flickering. These are typically not included with the bulbs.
