These are Strieter-Lite reflectors!

A set of these reflectors mounted on posts near the side of a highway dramatically reduce the number of deer-vehicle collisions that may occur at dawn, dusk or night.

When a car passes, light from the headlights is directed toward the side and across the road.

This light is seen by deer that wish to cross the highway as a row of sequential lights coming from the reflectors.

This startles them and causes them to run away or wait until the vehicle passes before crossing the road.

Over 190,000 reflectors have been purchased and installed in 25 states and in 5 provinces in Canada.
