I don't do a lot of night riding. Sometimes I leave the house and when I come back it's just past dark. The park I ride in in the mornings is about a 4 mile trail around the lake. There's some sections that are heavily covered by trees and even with the sun out, it's fairly dark through there. I keep my lights on...flashing...the entire time, front and rear. I use some pretty basic, carbon fiber bottle cages and 2 Camelbak bottles.
