Busch & Müller Bike lamp IXXI

The IXXI is small and light - in terms of size, it measures up to the VDO tail light, for example. However, it is not the smallest and lightest battery-powered rear light on the market. The very long battery life of 15 hours, especially in relation to the size, is outstanding. This is where the IXXI stands out from comparable competitor products...

... The small Ixxi rear light is rather unspectacular. It is small, has good side visibility and is sufficiently bright. Busch & Müller states a battery life of 17 hours. The bracket and cover unit is somewhat unusual. It is made of a soft material that can be pushed to the side to access the USB socket. It is attached to the seat post with a rubber band.

Bicycle rear lights: A lot of good things in the back Of the six rear lights tested, we can recommend most of them. All six red lights provide sufficient visibility in the dark, but we found big differences in individual test points. For example, one model lasted a long 22 hours, while another rear light ran out of juice after only 5 hours...
