Lights

Are also handy for unlit country roads anywhere outside of the smoke where you need to see where you're going.

Very true, I hope the "dipped" mode on my strada isn't blinding still...gonna have to test that out in more detail tomorrow.

I was talking about the rears specifically. I've got a fuck off front light for charging down pitch black country lanes, but I do angle it down a little, and often switch it to the lowest setting if I think there's a risk of blinding oncoming traffic of any shape or form (and also if I'm in a group and not on the front); or it's a flat well defined road; or it's a braw, bricht, moonlicht nicht; etc.
