Back in the day I used a sidewall bottle dynamo, and I disliked how the lights would turn off when I stopped (which is when I most want them on, many stops are at traffic lights and intersections). People used to rig up large capacitors to power the lights through stops, but I'm not electrically inclined enough to DIY. Are any of the modern dyno solutions equipped with reserve capcity to keep the lights on during stops?
