There’s no excuse for getting caught out without your lights when the Cateye Nimas are this handy, cheap and effective. Small, simple and strong is how Cateye refers to them – for good reason. The Nimas’ semi-transparent casing lets the light shine through out the sides, and they’re easy to mount anyway, with the heavy-duty band attachment. Four modes and simple to operate by just pushing and clicking, the Nimas weigh 20g each, including the supplied replaceable watch battery.

Price: £21.99, available from Cateye.

Best Price: £13.19, available from Sports JW Ethans.
