General Description: Deer warning whistles are ultrasonic devices designed to prevent collisions with wildlife, especially deer. Made of high-quality ABS plastic, these whistles withstand extreme outdoor temperatures and emit sounds that alert deer before they cross the road. Technical Specifications: Material: Molded ABS plastic; Sound Type: Ultrasonic; Quantity: 4 warning devices and 4 additional bases included. Installation: Remove the adhesive backing and stick the whistles to the grille, front bumper, rearview mirror, or any flat surface on your vehicle. Ensure the larger ends face forward and the whistle is at eye level. The best location is where airflow is greatest, such as the grille or front bumper.

How it works: The whistles operate by using circulating air to produce sounds that warn deer, encouraging them to stay on the side of the road rather than crossing in front of a vehicle.
