The Acme Whistles TH147NP Siren Whistle is sometimes referred to as the cyclist's road clearer. This unmistakable whistle sound-from a design introduced in 1895 and patented in the same year-still finds numerous uses. From tribal dances to marine signaling, this complex whistle is made with a watchmaker's precision.
