Deleted at Wurkkos request, because I made a mistake by posting a preproduction sample.
Thanks for the comprehensive write-up, there are a couple of similar designs but this seems particularly well thought-out.
It does indeed look like an LED swap(s) might be a bit tricky.
A plastic mounting bracket would be a good accessory to mount it securely on bicycles, obviously you can only use white or red, but as an auxiliary light it would be good as a backup to either front or rear.
good idea
sounds like a fun 3D printer project
or maybe it fits some existing mounts?
It does have a good strong Throw beam for forward use, and also a bike flasher (about 3 seconds interval)
The Solid or Blinking Red would also work to mark the back.
Does it have a blinking red (or/and white) mode?
Either way, a dual fuel AA clip light with High CRI is right up my alley.
