Car Deer Warning Whistles Airflow-Activated Set of 8

✔ Automatic airflow activation: The whistles produce an alert sound when airflow passes them at speeds above about 22 mph. Activation happens automatically while driving, with no switches or batteries to manage.

✔ Simple tape mounting: Clean the mounting surface, peel the backing, and press each whistle onto a bumper or grille. The included double-sided tape avoids drilling, extra hardware, and tool setup.

✔ Eight pieces for multiple vehicles: The eight-piece set fits cars, motorcycles, trucks, and RVs, allowing more mounting points to be covered. Compact ABS plastic whistles blend into bumpers or grilles and are made to withstand weather and road vibration.
