Bicycle Light Holder w/ quick-release

I had a nitecore srt5 lying around from my time in the army, it's one hell of a torch and I wanted to mount it to my bicycle. I didn't want to leave it there permanently and leave it open to the world to take.
-- so the issue here is i have something I want to mount securely, but have it easy enough to remove when I'm not using it. The answer was a quick-release utilising removable zip-ties.

This light holder comes in three parts. The top and middle section are screwed together around your handlebar (I lined the inner part of these with heatshrink to prevent it from scratching my bicycle handlebars)

A releasable zip tie goes through the holes in the middle section, around to the bottom. I found it's best to cross these (let me know if you need a more detailed description, or if you need pictures of the zip-ties used)
