SINGARO 8 Pack Deer Whistle Warning for Horn Unit, Suitable for Cars, Trucks, Motorcycles

Put on my car after I hit my first deer. So far so good, not full proof but helps.

Arrived as described. We used these when I was a Recruiter in IOWA in the late 80"s. had over 15 deer attacks in 3 months, placed these on the Cars and for the next year that I was on duty no more Deer attacked out Cars.

good price

I like the design of these as you can place them easily in those difficult areas that newer cars/suv's have. Just make sure you have good air flow through both whistles.

They went on super easy, but do they work? Don’t really know. Lol

Everyone I know that nay says the effectiveness of deer whistles, always hits a deer. I have always used deer whistles on all my vehicles and I never have hit a deer.

We live in an area with an over population of deer. Before bought these we had 2 deer run into our cars. Since we installed these we have not had any deer encounters, so either they work or the deer are done hitting our cars. I choose to play it safe so I will keep using them. We have 2 on the motorcycle.

As someone who has unfortunately collided with deer twice—each time with a different vehicle—I can confidently say this product did not work for me. After installing the device, I encountered two deer on separate occasions. Neither reacted to the presence of my vehicle, and they showed no signs of being alerted or deterred. Based on my experience, this product did not deliver the intended results. I would recommend relying on caution, awareness, and perhaps a bit of luck rather than depending solely on this device.
