The light is wired from the headlight. The wire goes down the downtube, under the bottom bracket, and is held in place under the fender with a series of clips meant for this purpose.
Brooks saddle and toolbag. Never carry on your person what you can carry on the bike. Never had a tool stolen off this bike.
