The switch knows of only one or with sensor. It lacks the ability to turn the lights on permanently. This may for example increase on a cross-country trip in the rain the visibility.
Not high I feel the two permanently mounted cable. The taillight is instead plugged into the housing at two ends of the cable. Heat Shrink were with me not there, just no cover for the lamp holder - these it is probably only the Luxos it. This can be of course with a cable tie fix, but is not very elegant.
Nicely done, the status LED in the switch on the back. So you can easily check if the light is on while driving.
Who does not wish to stand the light, can be accessed safely. For me, it is relevant to safety and leads to the devaluation on three stars because not all the achievements of recent years have been well implemented.
