100% of my riding these days is commutting and I leave my lights on low during the day, LightOn! brand. When I was skinnier and riding faster I'd turn the dyno lights off going up hill relying on helmet lights then switch the dyno on on flats. I can sense the difference but it's not a significant one . If I was doing fast group riding I wouldn't use one but for solo riding and giving cars one less excuse to turn into me from the opposite lane I'm all for it.
