Replacing bar-end plugs, the Lumos fit inside your bars and leave just a switch, rear and front facing lights poking out.

In principle, Tacx has come up with an amazing product. The twin lights are just so much easier for road users to spot and mark your bikes widest point. But because bar ends are so exposed off the bike secure fixing is vital and this is where the Lumos is let down.

With a basic plastic plunger containing an AA battery, fitting isn’t universal and without resorting to electrical tape isn’t very secure either.

A great idea let down by a Heath Robinson attachment – live with that and they’ll probably save your life.
