M4 SERIES

The M4 lighthead features a compact rectangular design that packs a powerful punch, delivering high-intensity illumination ideal for fire, EMS, law enforcement, and commercial vehicles. Like others in our popular M Series®, the M4 features Linear Super-LED® technology for bright, consistent light output, providing superior visibility in critical situations. This lighthead incorporates Dynamic Variable Intensity™ (DVI™) light patterns, automatically adjusting brightness levels during nighttime operations. This feature enhances safety by gradually increasing or decreasing light intensity, effectively alerting oncoming traffic to the vehicle’s presence and creating safer scenes. Available in both single- or dual-color models, the M4 can be configured for primary warning or a combination of primary warning and scene lighting. Its hard-coated, impact-resistant lenses ensure durability against sand, sun, salt, and road chemicals, making it a reliable choice for any environment.
