Powerhouse DeLuxe Super Siren by Fedtro is new, unused and endorsed by Mickey Mantle! This 12V DC siren was designed as a universal siren/horn that could be mounted and used on virtually any type of automobile or boat. New Old Stock accessory appears to have had its box's original strapping removed for inspection but is as new as they come. Take it from Mickey, "Fedtro.... proven sound around the world."
