This thread reminds me I'm long overdue for a greatly needed head clearing night ride and still have a roll of 3M reflective tape and some reflective dots I've meant to apply. I keep stalling because I haven't actually cleaned my bike(s) in forever and whenever I do it's because I'm swapping something or another and then wait to be sure I want to keep the build before I further accessorize.
I really enjoy night rides and being fortunate enough to reside in a complex directly across from trail access to a network of multiuse trails through a sprawling park mostly consisting of open meadows means leisurely riding under nothing but the moon and stars with little need for much lighting except for the few sections that run though more heavily wooded areas with a full canopy, Though I've tended to not venture too deep on the longer loops any longer and more or less stay nearby the more open trails which also intersect the local road crossings to allow easier detours and bail-out options since the park closes at dusk.
I have not yet ventured into Dyno or generator hub territory, although I did have prior plans to attempt an LED set up with a vintage Sturmey Archer Dynohub on an abandoned 3 speed project, but that fell through for unrelated reasons I won't get into here. For lighting I have a couple Princeton Tec Eos lights which have 3 brightness settings and the brightest does a pretty good job lighting up the trail under the darkest canopies in our local trails. I keep one mounted on the bars (currently on a drop bar single speed) with a second on the helmet for peeking around the curves during the darkest parts. I've played around a bit with light placement and although I really liked having a light mounted low near the wheel since it really highlights any irregularities or obstacles in the trail ahead, I really didn't care for the shadow from the wheel/tire on one side. I tried a fork crown mount on my recent build but it was awfully close to the tire and offered neither the same detail of the terrain like low beam near the hub or midfork mounts nor the convenience of the bar mount for easy on/off for when riding in those open air moon lit smooth trail sections where I really enjoy the complete lack of any artificial light and a leisurely pace. This is all a very personal approach for my particular route and if I were doing more commuting or riding after dark in busier areas and with more car traffic I think I'd already have converted to a generator of some sort.
The Eos 'Bike' models I have are very outdated and likely have long been replaced with newer models but I've no plans to upgrade until they meet their demise and still run on a few AA batteries (I think, should probably double check and refresh with the time change that just occured since I can't recall when I last put fresh batteries) and I really liked the multiple mounts they came with: bar mounts with rubber shims, helmet mount with velcro strap, plus an elastic headband for regular headlamp usage. If/when I do replace I'll look for something rechargeable, so the consumption of standard batteries is certainly the biggest drawback.
I have a back-up Planet Bike Beamer light mounted similarly to the handlebars of another bike but it comes nowhere near the brightness of the EOS so I rarely use this one alone and try to remember to bring the helmet light to supplement whereas if I take the Eos equipped bike I'm otherwise more confident with just the single bar mounted light.
Now I just need to get back out there one of these nights.
Best,
