Setup and Installation
Follow these steps for proper installation of your ASPL Strobe Light Bar:
- Choose Mounting Location: Select a flat, clean, and metallic surface on your vehicle's roof that allows for maximum visibility of the light bar. Ensure the surface is free of dirt, dust, and moisture.
- Secure the Light Bar: Place the light bar firmly onto the chosen surface. The 2x7 powerful magnets and rubber suction cups will provide a strong hold. Ensure all magnets and suction cups are in full contact with the roof. For added security, the base allows for screw fixation between the magnet and the light bar to prevent long-term detachment (screws not included, user discretion advised).

- Route the Power Cable: Carefully route the 5-meter (16.4 ft) power cable from the light bar into the vehicle's cabin, ensuring it does not interfere with doors, windows, or other moving parts. Avoid sharp edges that could damage the cable.
- Connect to Power: Insert the cigarette lighter plug into your vehicle's 12-24V cigarette lighter socket.
Operating Instructions
The ASPL Strobe Light Bar is designed for simple and intuitive operation.
- Power On/Off: Once connected to the vehicle's cigarette lighter socket, use the ON/OFF switch located on the cigarette lighter plug to power the light bar on or off.

- Select Flash Pattern: The cigarette lighter plug features a dual adjustment switch. Press the dedicated button (often labeled 'Mode' or similar) to cycle through the 16 available flash patterns. The light bar will remember the last selected pattern even after being powered off.
Maintenance
Regular maintenance will help prolong the life and performance of your strobe light bar.
- Cleaning: Periodically clean the light bar's lens and housing with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the plastic.
- Cable Inspection: Regularly inspect the power cable for any signs of wear, cuts, or damage. Replace if necessary.
- Mounting Check: Ensure the magnetic base and suction cups remain securely attached to the vehicle's roof. Re-position or clean the mounting surface if the grip weakens.
- Condensation: While the unit has an anti-condensation drain port, minor condensation may occur in extreme temperature fluctuations. This typically dissipates with use. If persistent, ensure the drain port is clear.
