It was one of those people who walk their dog early in the am down the road past my house. No light, no reflective clothing, dressed in black, even the dog was black. I was moving into the bike lane to let a car pass, and as I entered the bike lane, surprise there she was. After an oh, s#%t, I yelled at her to get a light. This is the third close call on this stretch of road. If I had brighter lights I would have seen her, if there wasn't a car I would never have seen her. moral of the story is I need better lights. At least then I can see them farther away and not be surprised. I'm thinking 3000 lumens what do you guys think?
