I had one on a racing bike. When you engaged it, the mechanical load was noticeable in the form of the increased effort necessary to pedal the bike. Also, when you stopped, the power stopped and your lights went out (a safety issue). I ended up removing and discarding it. I replace my original battery powered lights. The batteries had to be replaced frequently, however I always had light when I needed it and I could pedal as easily at night as I did during the day.
I remember the light going off when I stopped peddling. My father hooked up a battery in the line but that was before the days of rechargeable batteries, and the batteries died. In the late 1950s when I was a patent examiner we had two categories for classifying batteries. Rechargeable (car batteries) and non-rechargeable (flashlight batteries). We had to group the rechargeable (D, C cells etc.) with non-rechargeable batteries. The Patent Office classification system eventually caught up with the technology.
