Online shop Wiggle has started selling a tasty little accessory in the form of the Benex wind-up front light.

Three LEDs can be set to flashing or constant and, as you?d expect, they offer good quality light.

With a battery and charger you can use it in the normal way, but if you run out of power a minute of winding will give you 30 minutes more light ? genius!

Contact where the Benex is currently selling for £14.99.
