The Uno is a good little commuter light. Not much wider than the AA battery that’s used to power its single LED, it easily ﬁts into a pocket or a bag and, because you need to hold down the button to turn it on, there’s little danger of it accidentally turning on as you carry it around.
It uses the same simple clamp – ﬁtting both standard and oversized handlebars – common to much of the Cateye range. With constant and ﬂashing modes, it gives out a narrow but bright beam with good side-on visibility.
You could ride without street lights at a push, but it’s in its element in the urban environment. It’s also available in black or white, so could complement your components.
