3. Operating Instructions
The LF-300B H13 controller operates based on a simple power cycle sequence to switch between steady light and strobe modes.
- Normal Operation (Steady Light): Turn on the headlights or connected LED lights. The lights will remain steadily on.
- Activate Strobe Mode: To activate the strobe mode, turn off the lights, then quickly turn them back on. The connected LED lights will begin to flash in a continuous strobe pattern.
- Return to Normal Light: To return to normal steady light, turn off the lights again, then turn them on. The lights will revert to their steady-on state.
This controller is compatible with single-color, 2-color, and 3-color lamps, allowing for versatile lighting effects.
4. Maintenance
The Airshi LF-300B H13 LED Flash Strobe Controller is designed for durability and requires minimal maintenance. Follow these guidelines to ensure optimal performance and longevity:
- Regular Inspection: Periodically check the wiring connections for any signs of wear, corrosion, or looseness. Ensure all connections remain secure.
- Cleanliness: Keep the controller module free from excessive dust, dirt, and moisture. If cleaning is necessary, use a dry, soft cloth. Avoid using harsh chemicals or abrasive materials.
- Environmental Protection: While the unit is designed with corrosion and heat resistance, avoid exposing it to extreme temperatures or direct water immersion beyond its intended use.
- Avoid Overloading: Ensure the connected LED lamps do not exceed the controller's maximum power rating of 50W. Overloading can lead to premature failure.

- Verify the power supply voltage is within the 9-30V range.
- Test the LED lamp directly to ensure it is functional.
- Check for any blown fuses in the vehicle's circuit.
- Strobe Mode Not Activating:
- Ensure you are performing the power cycle (off, then quickly on) correctly to trigger the strobe mode.
- Confirm the controller is receiving consistent power.
- Lights Flickering or Malfunctioning:
- Inspect for loose or corroded connections.
- Ensure the total wattage of the connected lamps does not exceed 50W.
- Check for any damage to the controller's casing or wires.
If problems persist after following these steps, contact customer support for further assistance.
