Improve on-road visibility during emergencies, roadside assistance, and work-zone traffic control with this 240-LED mini strobe light bar compatible with car / truck / trailer / RV / caravan / boat. The magnetic base uses 2 heavy-duty magnets to attach securely to metal surfaces such as a vehicle roof for quick setup with no drilling, making it easy to install, remove, and store when not needed. Powered by 12 V DC at 15 W, it plugs into a standard vehicle cigarette-lighter port and includes an approx. 7 ft power cable to reach the dash. A single-button control lets you cycle through 8 flash patterns to match different warning and visibility needs. Built in a compact housing measuring 11 in long x 5.5 in wide x 2.5 in tall, it is designed for durable, waterproof performance on vehicles, worksites, and marine environments, and can also be used for events such as night parties or light shows. Strobe-light use on vehicles may be regulated by federal, state, and local laws; check applicable rules before use.
