The Alternating Strobe Module enhances motorcycle visibility by creating an attention-grabbing flash pattern when the brake is applied. It alternates the strobe effect between the left and right side lighting accessories, ensuring a dynamic, eye-catching display. With easy-to-use switches and a dial, riders can choose from 4 different flash patterns and adjust the flashing speed to their preference. This module is the ideal solution for riders involved in parades or group riding events, adding both style and safety to any ride. It includes one output for each side, supporting one plug-and-play light per side. For more lights, you can remove connectors to hardwire or add Extension Harnesses (sold separately) to connect up to three lights per side.
This module does not affect factory brake lights. To add flash effects to OEM lights, use a separate Magic Strobes™ Brake Light Flasher (sold separately). Note: Flashing brake lights may not be legal in all areas. Check local laws.
