Lights and clutch use.

Bear in mind that the headlamp can be seen only from in front. Hi-viz jackets and waistcoats can been seen from all angles (though not so well from the front if you have a tall tinted screen).

Look at the next person you see wearing a vest and decide if it is worth wearing on a bike. In most cases, it gets lost behind the screen etc, And even a rucksack in on elocal lads case that I see of an evening !!

Got to be a jacket IMO.
