Federal Signal MB1 LED Message Board – Programmable Public Safety Messaging

The Federal Signal MB1 LED Message Board provides a versatile, high-visibility messaging solution for police, fire, utility, and other emergency response vehicles. Designed to communicate important warnings and traffic information to motorists and pedestrians, the MB1 displays programmable LED messages to improve awareness around emergency incidents, road closures, traffic hazards, and work zones.

Programmable Public Safety Messaging

The MB1 includes 60 preprogrammed messages covering common traffic and emergency situations, including lane closures, detours, accidents, and roadway hazards. With storage for up to 500 custom messages, the system allows agencies to tailor displayed information to their operational requirements.

Federal Signal's PC-based configuration software enables users to create and organize custom messages, including scrolling, flashing, and directional displays. Programmed message sets can also be transferred between compatible MB1 systems, helping maintain consistent messaging across a vehicle fleet.

Convenient In-Vehicle Control

The MB1 features a dedicated, internally mounted control head with tactical push-button controls and an LCD display. Operators can quickly select and activate messages from inside the vehicle, while adjustable display brightness and control head settings accommodate different operating conditions.

Durable Construction and Flexible Installation

Built with a rugged polycarbonate housing, the MB1 is designed for demanding public safety environments. Available in Amber, Blue, and Green LED configurations, the message board supports installation on compatible vehicle lightbars, interior mounting locations, and other suitable vehicle structures using designated mounting hardware.
