Note that there is a version for dynamo, the 4375. I chose to test the battery version first because I figured that being able to open it for the batteries might mean access to the electronics/optics without damaging it. As the optics are not good enough, I will not review the dynamo version.
See the camera settings page for more on the setup and settings to make pictures of the beams of taillamps.

Visibility from various angles (0°, 45°, 90°, 135°) [ 0.5m, zoom x3, F3.5, ISO80, 1/250s & 1/60s ]:
The optics are essential for any bicycle lamp, and in that respect it fails quite badly. It has a very strong point source of light, which is very bad for a proper taillamp. Power use?. The construction is good, the mounting hardwars is all stainless, also good. Switch is protected from moisture with rubber cap.
