An observation about lights
Late last summer, when I found myself riding in the dark, I bought myself two lights after doing some research, mostly here on the forum. What I bought was a Lezyne 450 lumen (claimed and real), and a cheaper Keygos Cree XM-L light (1200 claimed, but probably only about 500-600). These lights were deemed blindingly bright by everybody that commented, usually in a good way. I really stood out in the crowd, and was by far the brightest light out there.
I was riding tonight and was just noticing how many riders have lights that are just as bright now. These things have caught on. It is all for the good.
