Hello – I recently got a new bike and found that when my rear rack is loaded (with a tent etc.) it blocks my back light on seatpost.
So I made this little bracket that allows you to attach to the back of the rear rack, and I thought it might be useful for others on here.
It's designed for a Lezyne light and a Tubus rack but should work with most lights that attach to a seatpost. The tube is 22mm diameter and the bolt holes are 6mm with a 50mm centre spacing. It weighs about 18g when printed in PETG.
The link has files for 3D printing and also SolidWorks files if you want to adjust any sizings.

Cool. Busch and Muller also make lights that fit that metal plate on the back of the Tubus racks
Thanks – whilst the two-hole mounting plate on the back of most racks is designed for a reflector/light to be fitted, most lights that fit are somewhat weak (designed to meet StVZO regulations) and lack the advanced technology (radar for example) available in other form factors.
I don’t have a 3D printer but I support your effort to solve this problem. There are hundreds of seat post mounted rear lights but only a handful of rack mounted rear lights.
Awesome! Can you make them in black? Do you sell them?
