Fellow cyclists, please make sure you aren't blinding everyone around you
Being able to see is great and not getting run over is also great, but other people need to be able to see too. Please point your lights down and don't use flashing lights, especially in the dark. Headlights with a cut off are great if you can afford one.
Flashing headlights are actually illegal and all flashing lights actually make it significantly harder to judge speed and distance. There's nothing like trying to see when someone is shining a strobe light in my eyes.
(Drivers with poorly aimed headlights also suck)
