As the title covers, I'm in search of a tail light that can clip or attach to a seat wedge bag. I'm using the Bontrager Pro Medium QC Seat Pack. I wish to mount a light on that back loop with the B symbol.
I'd prefer something thin and light, yet bright. USB chargeable. Something decent. Something that is designed with this purpose in mind, and not something I rig up. Something that mounts clean, sturdy, flush, and no sag.
So far I've only come across the Lezyne Zecto Drive Taillight that has a clip or tube strap option. Seems good, but I was wondering what my other options might be.
Another option I considered is getting the Bontrager Tail Light Seat Pack Clip and https://www.trekbikes.com/us/en_US/e...?colorCode=red.

It just seems my current tail light on my seat post is somewhat obscured by the tire and bag from the rear.
