Just an observation I've made, there aren't too many people who cycle early morning or evenings wearing reflective jackets or other items of visibility other than their front and rear lights. Firstly, is there a reason for this? Also, given that the largest part of a cyclist on a bike is the actual cyclist, would it not make sense for the cyclist to be most visible? The reason I ask is I am fairly new to cycling and wanted to understand if items like the two jackets below with LED's are considered taboo? or not practical for some reason? or just not readily available? With Winter fast approaching and most of my cycling to occur during darker periods I am hoping to understand what options are available to me or recommended to ensure I remain safe on the road. Not sure if I'm alone here or if others share the same thoughts or interests in items like the below?
