Knog Plug in the test: The simple LED rear light from the Australian company Knog fits on every bike - whether city bike or racing bike. You can find out how the Knog Plug performed in our detailed test here.
The round LED taillight with a soft plastic housing is available in three colors (black, gray, red). We took a closer look at the StVZO-compliant version of the rear light.

Our test impression of the Knog Plug
packaging and assembly
The Knog Plug is delivered in small, space-saving packaging made of recycled cardboard and some plastic. In addition to the rear light, the scope of delivery also includes a Velcro strap and an adhesive strip for attachment. A micro USB cable for charging the lamp is not included; However, the lamp can be charged with any standard Micro-UBS cable. With the Velcro strap and the adhesive strip, the lamp can be easily and safely mounted on a wide variety of seat posts. However, hacking the Velcro onto the lamp with the two plastic buckles was a little difficult. Since you have to completely dismantle the lamp to charge it, a more uncomplicated assembly system would be desirable.
Operation and battery life
Operating the Knog Plug is very simple and intuitive, as there is only one very large and smooth-running on/off button on the bottom of the lamp. In the StVZO-approved versions like the ones we tested, there is only one mode in which the rear light lights up permanently with 10 lumens. With a slightly longer press on the button, the lamp can be switched on or off - very simple. The battery then lasts for around 3,5 hours, which is quite enough for everyday use. A small indicator light on top of the taillight illuminates when the battery level is low. However, the indicator light does not show the current battery level, as is the case with other taillights in our test series. To charge, the lamp must then be completely removed as the micro USB port is hidden under the seat post attachment. The charging time is also around 3,5 hours.
With a weight of 31,75 grams including the holder, the Knog Plug is still pretty light. The 180 degree side visibility is fine to be seen better in traffic. This taillight does not have a brake light function or an auto sensor function, but it offers simplicity and a slightly lower price.
What is allowed, what matters?: Battery taillights
Battery-powered rear lights: When it comes to lighting, cyclists today benefit from uncomplicated rules and high-quality technology. However, it can't hurt to know what the StVZO requires - here's a brief overview. Cyclists in particular have benefited from the new version of the legal regulations on bicycle lighting in June 2017: the requirement to carry battery-powered lights has been lifted; Today, bicycles only have to be used “during […]
