I’m shopping for a new seatpost mount taillight. I’ve been using battery powered “disposables” that are cheap ($12) and pretty bright for extra light for certain sections of my ride. (I leave my helmet mounted Vis 360 on all the time, but sometimes in rain and certain road conditions, I just want another rear light on there to make sure drivers see me and get some depth perception.)
Problem with the disposable lights is that they aren’t waterproof. Maybe I won’t have as much trouble since I put on the fenders, but I found that most disposables didn’t last more than about 6 months before the water gets inside and messes them up. Since I don’t run them that much, they are breaking on me before the batteries go down.
I’d like to find a decent truly waterproof, rechargeable taillight that I can depend on to last for a long time, be reachable to turn on and off, and be bright enough to be a solid spare in case the Vis 360 ever craps out (but doesn’t necessarily have to be supernova bright). Suggestions?
