M737-LED

Bi-Directional LED Safety Photocell Light — 4,000+ Hour Runtime

The M737-LED-4D is a bi-directional LED safety light for long-term barricade and rail protection that runs more than 4,000 hours on four D-cell batteries, using a photocell to turn on at dusk and off at dawn, an external waterproof power switch with an LED indicator so crews can confirm in daylight that the light is armed, and an internal tilt switch that shuts the light off in the down position to prevent battery drain when a hinged flag or barricade is lowered, behind an optic lens that illuminates the full lens face over a conformal-coated PCB. Available in blue (M737-LED-B-4D) or red (M737-LED-R-4D).

Best use case: Best for long-term barricades and fixed hazards in rail yards, construction sites, road work, utilities, and industrial facilities, combining automatic dusk activation with 4,000+ hours of battery life.
