Whelen® U-Series DUO Blue/Amber SMOKED, 10-30V, SAE

The Whelen U-Series™ sets a new standard for compact, high-performance warning lights. Designed for seamless installation beneath side mirrors or along vehicle exteriors, the U-Series delivers an impressive 180° light spread through its innovative U-shaped “lay-flat” optics. The result is outstanding visibility and safety from every angle — crucial for first responders and professional fleets operating in dynamic environments.

With a sleek, low-profile form factor, the U-Series blends effortlessly into modern vehicle designs while maintaining maximum output. Available in DUO™ and TRIO™ color configurations, and with a choice of clear or smoked lenses, it provides exceptional flexibility for all mission types.

Engineered to endure the toughest conditions, the U-Series features conformal-coated electronics for protection against moisture and vibration, as well as hard-coated lenses resistant to sand, salt, and UV damage. It synchronizes seamlessly with other Whelen lighting systems and supports 35 Scan-Lock™ flash patterns, DVI™ variable intensity, and Steady-Lock® functionality for integration with Whelen Core® systems.
