The Trailblazer Electronic Deer Alert is a must for any car or truck that gets driven at night or through places with high deer populations. This electronic device is 10x safer than traditional deer whistles and emits a sound that deer and other animals can hear up to 1100 feet before you get there. Plus, you can hear the sound too, so you know the Trailblazer Deer Alert is working. The kit comes complete with wiring, switch and bezel so you can install it almost anywhere out of sight.
