Built with a legendary 120-watt rotary mechanism and dual high-intensity strobe tubes, this beacon delivers a brilliant, penetrating flash that cuts through daylight, fog, and adverse weather conditions to ensure your vehicle is seen and recognized from a distance.

Ideal for law enforcement, fire apparatus, ambulances, construction vehicles, and snow plows, the 141ST-120R provides the ultimate in safety and scene presence. Its robust, all-metal construction and proven reliability make it the go-to choice for professionals who depend on their equipment in critical situations.

Key Features & Benefits:

• High-Intensity 120W Rotary Strobe System: Features a powerful motor that spins two parabolic mirrors, creating a dynamic, omni-directional warning pattern. This rotating flash is significantly brighter and more attention-grabbing than static lights.

• Dual 45-Watt Quartz Strobe Tubes: Produces an incredibly intense, wide-angle flash. The dual-tube design ensures consistent, reliable output and provides built-in redundancy; if one tube fails, the other continues to operate.

• All-Metal, Weather-Tight Housing: Constructed from durable die-cast aluminum with a corrosion-resistant finish, this light is built to withstand harsh environments, extreme temperatures, and the rigors of daily use. It is designed to be water-tight and dust-proof.

• Universal Mounting & Compatibility: The low-profile “pancake” design allows for flexible installation on vehicle roofs, decks, or in a variety of lightbars. It is compatible with standard 12V DC vehicle electrical systems.

• Multiple Flash Patterns: Operates with a dedicated SN200/SN400 series power supply (sold separately) to deliver selectable flash patterns, including single-flash, double-flash, and quad-flash modes for versatile warning scenarios.

• Distinctive Clear Dome with Colored Inserts: The light is supplied with a clear polycarbonate dome for maximum light output. It includes a set of snap-in, interchangeable colored filters (typically Red, Blue, Amber, and Clear) for compliance with local ordinances and operational needs.

• Industry-Leading Reliability: As a product from Federal Signal, the 141ST-120R is engineered to the highest standards of quality and durability, ensuring long-term performance when it matters most.
