BlackBurn Voyager 2.0/Mars Click light set review

In terms of visibility and also kicking out enough light to make progress with in the dark, the voyager front light in this set is really very good. The rear light, although pretty good in performance, suffered from water and road grime getting into the switch mechanism.

The problem is that the lens is the switch, you depress it to operate, and the gap between lens and body is right in line of the rear wheel spray when mounted on the seatpost. This led to us not being able to turn the rear light off.
