The M6 lighthead provides high-performance warning and scene lighting for fire, EMS, and DOT vehicles. Engineered with our Linear Super-LED® optics, the M6 offers bright, consistent lighting for both front and rear vehicle applications. Available in SOLO™ and DUO™ models, the M6 also features Dynamic Variable Intensity™ (DVI™) light patterns, which adjust brightness levels during nighttime operations, enhancing safety by gradually increasing or decreasing intensity. The M6 also incorporates our patented E Block™ technology, preventing air and moisture from entering the unit for long-lasting reliability. Constructed with hard-coated lenses, it resists damage from sand, sun, salt, and road chemicals, making it highly durable in demanding environments. This lighthead is easy to install and can be mounted vertically or horizontally, making it a versatile choice for any fleet.
