Whelen Mega T-Series
The Whelen Mega T-Series™ is a large-format surface-mounted warning lighthead designed to deliver powerful visibility in a slim, low-profile package. As the largest member of Whelen’s T-Series family, the Mega T-Series is built for grille, push-bumper, and other exterior mounting applications where strong warning performance is needed without adding bulky equipment to the vehicle.
At just over 11 inches long and only 1/2 inch deep, the Mega T-Series provides a clean, unobtrusive appearance while still offering the versatility and reliability expected from Whelen T-Series lighting. Available in SOLO™, DUO™, and TRIO™ configurations, it can be used for primary warning, perimeter warning, or supplemental scene-lighting applications on law-enforcement, fire, EMS, utility, and other public-safety vehicles.
The Mega T-Series also incorporates advanced Whelen technology including Dynamic Variable Intensity™ (DVI™), E Block™ Protection, and Steady-Lock™ functionality for dependable operation in demanding environments. Clear and smoked lens options, multiple color combinations, and optional mounting accessories allow the lighthead to be configured for a wide variety of vehicle applications.
