Ambulances, fire trucks, and other emergency vehicles, construction equipment, road service vehicles, and other service vehicles are equipped with the Pulse-XL, which emits a bright warning light with 12 LEDs. Its water-resistant construction and UV- and impact-resistant polycarbonate plastic ensure long-term use in harsh environmental conditions. The Pulse-XL offers the option of either a passive design controlled by an external electronic circuit or an active design using a built-in circuit. It can be used independently or synchronized with a variety of its own models or with other ARMAS warning systems. The Pulse-XL, supplied as standard with a single-color warning light, is also available with a two-color warning option.
