Thanks again for your story, @

People here talk about carrying a spare headlight, and I think it's kind of unnecessary. But I started carrying one anyway once I found one that is cheap and small and works well. It's always in my bag. I've had to use it twice now. A month ago, I had forgotten to bring a headlight, and I have to move it from bike to bike since I have so many bikes. But I had my spare with me, so that made me feel good going home. Then last night, I couldn't find my main headlight, so I used my spare. It turns out I had left my main one connected to the charger. See, this is why I like dynamo lights better. I just can't afford to have them on all bikes, and I also like to keep some bikes down to minimal weight.
