Whelen Howler Low Frequency Siren - Universal

Whelen Howler Low Frequency Siren - Universal

Command the attention of deeply distracted drivers with the Whelen Howler Low Frequency Siren system, designed for universal application on heavy fire apparatus and custom emergency vehicles. Modern vehicle cabins are heavily soundproofed, often rendering standard high-pitch sirens completely ineffective against loud music and cell phone use. The Howler generates deep, penetrating, low-frequency bass tones that easily penetrate thick glass, ensuring surrounding motorists physically feel your approach.
