Features Quick Connection and Sturdy Quickly connect and disconnect the base for easy installation and disassembly. The round handle of the base is designed to be very long, making the bottom of the whip light very sturdy and stable on the car. The positioning hole prevents the whip light from rotating and causing the wiring to become tangled. Better Battery Protection Provide whip light rocker switch for safe use. You can first connect the whip light to the rocker switch instead of directly connecting it to the battery to avoid depleting the battery. One-to-One Remote Control You can freely set/release the one-to-one remote control mode. Before connecting the whip light to the power supply, press and hold the ON/OFF button, and then turn on the power. When the whip light turns red/green, the one-to-one remote control mode has been successfully bound/removed. Earthquake Resistance The spring base can increase flexibility, achieve more swinging, and greatly reduce the risk of base fracture.
