We called those "Leg Lights" when I was in college 40 years ago. Not sure if that was a brand name or just a description. I got through college using one of those for riding at night, but they don't hold a candle compared to any modern light (pun intended). The main advantage to them is that the light moves up and down while you pedal, making them more visible even though the actual light is quite dim.
