Riding horses in low light poses some obvious dangers, particularly in areas where they're forced to share the road with drivers who could become easily distracted. Sadly, for Tail Lights creator Sami Gros, it took a near-tragedy to inspire a solution.
"I was out riding my two horses with my best friend, and a car hit my friend and my horse. My friend was OK, but my horse suffered injuries that has made him unridable to this day," Gros told The Dodo. "I searched the internet for a product that would allow me to be seen for up to a half mile, and there was nothing out there. So I created one."
