5. Setup and Installation
The XRIDONSEN Strobe Light Bar is designed for easy installation on various vehicle types. Follow these steps for proper setup:
5.1. Mounting the Light Bar
- Choose a Location: Select a flat, metallic surface on your vehicle's roof for optimal magnetic adhesion. Ensure the area is clean and free of debris.
- Position the Light Bar: Carefully place the light bar on the chosen surface. The magnetic mounts, equipped with rubber suction cups, will adhere to the roof.
