A Highly Visible Rear Light — Knog Plug Rear Light

Searching for the perfect accessory to brighten your ride? The Plug is a rear bicycle light that harkens back to Knog's roots, using an over-molded soft-touch TPU in three fun colors. This light is packed with fresh technology like a low battery indicator and, like all Knog bike lights, it is fully USB rechargeable.

This is a light for every-day, for every ride, for everybody. Clever construction really takes this bike light above and beyond, as the domed shape allows for maximum clarity when viewed face on as well as improved side visibility. The simple large, soft-touch button provides simple operation — so you can turn this light on and off with ease without ever removing your gloves. Designed to work with all genres of bicycles from commuters to aero road bikes, the Knog Plug comes with three different silicone bands for securing it to the seat post.


  • Domed shape provides higher visibility
  • Easy one button operation
  • Low battery indicator
  • USB rechargeable thanks to the micro USB port
  • 3 seatpost-securing silicone bands included
  • Fits onto any bike, from lightweight road rides to heavy-duty mountain and gravel bikes
