promoting lights good or bad?

I used to think like this but it's complete bollocks. .

Chillout bro, was joking! I have a bike covered in reflective tape and would totally wear hi viz if having to ride sketchy roundabouts & dual carriageways regularly.

There is certain places like this that used to be on my regular routes, where even in bright daylight & taking primary, you could still guarantee cars running into your path and claiming they never saw you.
