I was thinking the same regarding the protective bag for battery box of the neon string whilst putting it inside the pannier with maybe a small damp box too. My trike will have a pair of wing mirrors on for visibilty but does wearing a protective neck brace restrict neck movement significantly?
Recumbents restrict your movements, in that you cannot turn your shoulders in the same way as you do on an upright. Wing mirrors make sense
All my trikes have them
