400 Series Plus Lightheads

Designed for lower-level mounting, the 400 Series Plus warning lighthead builds on the original 400 Series’ reputation for commanding attention with its versatility and performance. The improved lightheads have been refined to decrease wear and tear on a truck’s electrical system with a lower amp draw and stand up to severe weather with our patented E Block™ technology, which prevents air and moisture from entering the unit. Lightheads are available with steady or flashing warning lights, and SOLO™ or DUO™ technology. Vertically mounted 400 Series Plus warning lightheads used in DOT systems also include a fluted lens to enhance light spread.
