I know about the obvious stuff like a bright vest, blinking rear light and wearing light colored clothes but is there anything else that I need for when nightfall hits?
I recommend clear safety glasses. Especially if you live someplace dry. You don’t want dust or insects in your eyes. I hit a palo verde beetle once and it almost knocked my glasses off my face.
Eye protection is super important for daily bicycle use, no matter weather or time of day. A single speck of dust falling into the eye at the wrong time can cause a serious accident.
The more you ride, the higher probability of such thing happening. Not to mention wind drying your eyes, it can be serious pretty fast.
Not clear, but photochromic cycling glasses have been a god send for me.
I can wear them all the time, including inside a store, at night, during bright summer days, or during those rides that start before dawn/dusk.
Before that, i had dedicated clear and dark glasses, but they were highly inconvenient.
