2. Safety Information
- Ensure the vehicle's power is off before attempting any installation or removal of lights.
- Handle LED bulbs by their base to avoid touching the LED chips directly.
- Do not look directly into the illuminated LED bulb, as it can be very bright.
- If you are unsure about the installation process, consult a qualified automotive technician.
- Keep out of reach of children.
3. Setup and Installation
These LED festoon lamps are designed for easy replacement of existing halogen bulbs. Ensure you have selected the correct size (31mm, 36mm, 39mm, or 41mm) for your vehicle's application.
Installation Steps:
- Turn off Power: Ensure the vehicle's ignition is off and the specific light circuit is de-energized.
- Pry Lamp Shade: Carefully use a plastic pry tool or a small flat-head screwdriver (wrapped in tape to prevent scratches) to gently pry open the lamp shade cover.
- Remove Halogen Lamp: Once the cover is removed, carefully extract the old halogen festoon bulb. It may be hot if recently used.
- Install LED Lamp: Insert the new AHLTD LED festoon lamp into the socket. Ensure a secure fit.
- Test Functionality: Turn on the vehicle's power and test the new LED light. If it does not illuminate, remove it, flip it 180 degrees (LEDs are polarity sensitive), and reinsert it. Test again.
- Replace Lampshade: Once confirmed working, carefully snap the lamp shade cover back into place.

4. Operating Instructions
The AHLTD LED Festoon Lamp operates like your vehicle's original bulb. Once installed, it will illuminate when the corresponding circuit is activated (e.g., opening a car door for dome lights, turning on the map light switch).
- Voltage: Designed for DC 12V automotive systems.
- Light Color: Produces a bright white light (approximately 6500K).
- Applications: Suitable for dome lights, map lights, trunk lights, license plate lights, door courtesy lights, and other festoon bulb applications.
5. Maintenance
- Cleaning: If the LED bulb or its housing becomes dirty, gently wipe it with a soft, dry, lint-free cloth. Do not use abrasive cleaners or solvents.
- No User Serviceable Parts: The LED bulb is a sealed unit and contains no user-serviceable parts. Do not attempt to disassemble it.
- Replacement: Due to the long lifespan of LED technology, frequent replacement is not expected. Replace the bulb if it ceases to function.
6. Troubleshooting
- Light Does Not Turn On:
- Check the polarity: Remove the LED bulb, flip it 180 degrees, and reinsert it.
- Ensure the bulb is seated correctly and making good contact with the terminals.
- Verify the vehicle's fuse for that light circuit is intact.
- Confirm the vehicle's power is on for that circuit.
- Light Flickers:
- Ensure the bulb is securely seated in the socket.
- Check for stable 12V power supply to the socket.
- If flickering persists, it might indicate an issue with the vehicle's electrical system or a faulty bulb (rare).
