Needed a seat post bracket that was a little more secure than the rubber stretch bracket that came with my bike rear light+alarm.
My light+alarm model is A6 Pro which I got from Amazon. But I've seen the same design under many different brands and sellers including Aliexpress.
This light attachment "socket" is used by many generic lights, including some Rockbros designs,
a 5mm nut and bolt is needed.
Supports are needed - I used tree supports which were easier to remove cleanly.
The fit is a little tight, especially the initial turning to lock in.
I initially oriented my design the wrong way and had to redo it, but decided to include the original version in case someone's light is oriented the other way.
A little about the light itself: The light + alarm is really nice, and has a smart braking feature which uses an accelerometer to automatically turn the light's brightness up high when slowing down and braking. Additionally, the alarm function is really loud and charges with USB-C.
