Are bike lights even necessary? I mean, cant we just rely on our own visibility skills and road awareness to avoid accidents? Ive seen so many riders with lights that are barely visible from a few feet away, and it got me thinking - are we just wasting our money on these things? Ive read that some studies suggest that bike lights are more of a placebo effect, making riders feel safer but not actually reducing the risk of accidents. And whats with the ridiculous lumen counts on some of these lights? Is 1000 lumens really necessary, or is it just a marketing gimmick? Ive seen some lights that claim to be visible from a mile away - but what does that even mean? Are we trying to be seen by planes flying overhead? Can someone explain to me what makes a good bike light, and why I shouldnt just stick with my trusty old reflective gear?
