5. Setup and Installation

The AHLTD LED bulbs are designed for easy, direct replacement of original bulbs with a plug-and-play functionality. They feature a non-polarity design, simplifying installation.

  1. **Identify Bulb Type:** Confirm the correct bulb type (e.g., 1156, 1157, T20, 7440, 7443) required for your vehicle's specific lighting application.
  2. **Access Bulb Socket:** Locate and access the bulb socket in your vehicle. This may involve opening the hood, trunk, or removing a tail light assembly.
  3. **Remove Old Bulb:** Carefully twist or pull out the old bulb from its socket.
  4. **Insert New LED Bulb:** Insert the new AHLTD LED bulb into the socket. Due to its non-polarity design, it will work regardless of orientation.
  5. **Test Functionality:** Before reassembling, turn on your vehicle's ignition and test the light function (e.g., turn signal, brake light, reverse light) to ensure the new LED bulb is working correctly.
  6. **Secure Assembly:** Once confirmed working, reassemble any removed components.

Important Note: Some modern vehicles are equipped with CANbus systems that monitor bulb status. If your vehicle displays a "bulb out" warning or experiences hyper-flashing after installing LED bulbs, you may need to install a CANbus compatible resistor or decoder. Please check your car's manual or consult an automotive expert if you encounter such issues.

Socket Types

The bulbs are available in various socket types. Ensure you select the correct type for your vehicle.
