Eye-opening new perspective on my daily commute

In the seventies, Bill Rodgers, the marathon runner, had a line of running clothes that included a light jacket that was reflective. The jacket was a normal blue and grey in daylight, but at night, when lights hit it, it lit up like a Christmas tree. It was too light weight to wear on a motorcycle, but was great otherwise. I have never seen that technology used in any other application and wonder what happened to it.
