They work!

I have used deer whistles on my vehicles (cars, trucks and motorcycles over 40 years.


The most recent set that I installed are less visable, they are not as high as the others that I've used and they are clear plastic.

I live in an area where the deer population is very healthy. I usually see 3-4 on the drive into to town. The deer hear us coming, many times long before we see them, they stop browsing and perk their eyes up. As you get closer the deer becomes very alert, they turn away from the road and head into the area of safety.
