To a deer, standing between the oncoming glares seems safer because it doesn't see the entire car existing between the headlights.
They require no wiring, simply apply to the front of the vehicle (super simple instructions and illustration included). This product makes no sound noticed by human ears. It produces a sound audible to deer and the like, warning them of your vehicle's approach.
