Rear Light for Mudguard
Contains a single bright LED with a plastic lens to improve the visibility of the light.
Operates from two AAA cells
Position the light so that the LED faces directly towards the rear (not upwards at all because the idea is to be maximally visible to people at a distance).
Fitting the light requires two holes separated by 19 mm in your mudguard. One hole is filled by the bolt which is part of the light itself and the other by a plastic knob which prevents the light from rotating on your mudguard.
