Bike light seat post extender

youmagine

Most bike rear lights attach to the seat post, but a handy "seat wedge" bag that stores essential repair tools also sits under the seat. Unfortunately, this setup can block the view of the rear light. I recently purchased a Knog light, which casts a large beam when mounted in this location. While it's not a major issue, I wanted to find a solution that would address both problems at once. To solve these issues, I created a device that allows me to securely attach my rear light and seat wedge bag together, keeping the light perfectly vertical and visible from all angles.
