T-Series™
The T-Series™ lighthead delivers high-performance warning and illumination in a sleek, low-profile design with a depth of only 0.5” and a length of just over 5.0”. Available in SOLO™, DUO™, and TRIO™ models, the T-Series offers a variety of color configurations, each with a range of Scan-Lock™ flash patterns that enhance visibility in any situation. Built with our Linear Super-LED® optics, it provides bright, even light output while maintaining a slim, unobtrusive appearance. Constructed for durability, the hard-coated lenses resist damage from sand, sun, salt, and road chemicals, ensuring reliable performance in harsh environments. The T-Series synchronizes with other Whelen sync products, allowing for seamless integration across your fleet. With a simple 2-screw or stud surface mount and included black flange, it’s easy to install on emergency, utility, or commercial vehicles.
