An effective added layer of warning when used with your 100/200 watt siren amplifier. Howler provides deep, low frequency tones, which are able to penetrate other vehicles, alerting drivers and pedestrians of your approach. LOW FREQUENCY TONES FOR INTERSECTIONS AND HIGH RISK AREAS. 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.
