Lights

I gave away my Knogs (toads or something). To a mate who was cycling around lightless.

Despite having having external battery lights on the designated winter bike. I really missed them.

I've got a set of Knogs on my CX bike, and on my Langster purely because they are small, cheap, and effective enough to be left on each bike and provide light when needed.

I'll slap the Hope Vision One on the bars when intending on going for a ride at night, but for not having to think about it city commuting the Knogs are hard to beat in my view.
