Whelen M7 DUO Series Dual Color Warning Light

Whelen Engineering has added split-color functionality to their popular M7 Series warning lights to create the M7 DUO Series. As the name implies, this enhanced light now offers dual color warning lights in a powerful LED package. Like the rest of the M Series, this 7.6”W light is designed for high-visibility and features Whelen's advanced linear optics for wide-angle visibility no matter where you put it.

Suitable for vertical or horizontal orientation on a vehicle, the M7 DUO is ideal for emergency, towing and utility trucks where effective lighting is needed. Equipped with Whelen’s E Block™ and DVI technology, the M7 Series operates efficiently on 12/24V systems without excessive battery drain, providing bright, sustained lighting. Reduced power consumption means less strain on vehicle batteries.

Built for durability and reliability, this surface-mounted light features a hard-coated lens for reduced maintenance and long-term viability. Backed by a 10-year warranty, the sealed electronics and lenses make the M7 DUO Series resistant to damage from dust, debris and harsh weather. Count on quality and clarity over the life of the light and appreciate the minimized downtime due to unnecessary light repairs.

These SAE Class 1 lights are available with chrome or black bezels for added protection and aesthetics. Choose from 21 color/lens/bezel combinations and up to 64 ScanLock™ patterns. The light’s syncing capabilities allow users to adjust lighting to produce a cohesive signal at any high-traffic scene. This customization creates a highly visible, coordinated warning system that maximizes awareness and operational safety in different environments.
