+ Very bright, at least as bright as a dynamo driven standard taillight + Can the Luggage carrier be firmly mounted (if an appropriate disk is present), and then is always present + Batteries can be changed without tools + Weatherproof, with my bike, standing outdoors all year round, the last two years no problem with water penetration. + Recognizable only for insiders battery light, thus relatively safe from theft
