An added layer of warning for intersections and high risk areas when used with your 100/200 watt siren amplifier. Howler provides deep, low frequency tones, which penetrate other vehicles, alerting drivers and pedestrians of your approach.
__________________________
Howler is not a replacement to the vehicle’s primary siren; Howler adds a minimum eight second penetrating burst of low frequency siren sound for use in heavy traffic, intersections or other high ambient noise conditions.
