Busch & Müller IXXI 383 Rechargeable LED Bike Rear Light

Apparently this meets or exceeds the German standards for rear bike lighting. German drivers must be more attentive than British ones, because this light is exceeding dim, even by comparison with an old Cateye. More like the old Never ready rubbish, but a bit more reliable. Unless you have an obsession with meeting german standards (being road legal as some silly people call it), aaboid this and buy something effective.

Bit disappointed as does not work now after leaving my bike outside a few days...does not charge.

The switch stopped working and the light became unreliable - switching itself off randomly
