Setup Instructions
Mounting the Light Bar
The ASPL 16.8 Inch LED Strobe Flashing Light Bar is equipped with a magnetic base and suction cups for secure, temporary mounting on metal surfaces.
- Clean the Mounting Surface: Ensure the vehicle's roof or desired metal surface is clean, dry, and free of debris to maximize magnetic adhesion.
- Position the Light Bar: Carefully place the light bar on the chosen metal surface. The four strong magnets with thick rubber suction cups will provide stability.

- Note for Aluminum Vehicles: The magnetic base is not suitable for vehicles with aluminum bodies.
