400 Series Plus
The 400 Series Plus lighthead takes the reliable performance of the original 400 Series to the next level, offering enhanced visibility and durability for emergency, DOT, and utility vehicles. Designed specifically for lower-level mounting, the 400 Series Plus provides improved light output while reducing wear and tear on a vehicle’s electrical system, thanks to its lower amp draw.

The 400 Series Plus can be configured with steady or flashing warning lights, making it adaptable to various needs for fire apparatus and commercial trucks.
