Cateye ampp500 on dynamo light bracket using gopro extender

TLDR: Mounted the Cateye/Brompton Ampp500s on the dynamo light bracket using a gopro extender.

A bit of context, feel free to skip. I'm a proud owner of a 2011 M6RN on which I replaced the dynamo front wheel for a standard wheel, and removed the dynamo lights. Then, I ended up with a Cateye Ampp 500s, which as most of you know, is the same as the Brompton-branded front light. I like the light, mostly, and I tried to use it with the braket sold by Brompton to put it on the fork.

However, when used with that bracket, the light's vertical pointing cannot be adjusted and it can blind the incoming traffic, which can be dangerous for everyone involved. I could have tried to bend the bracket but opted for another path. Since I still had the dynamo light bracket, I got this Cateye H34 mount adapter that I could place on it (picture 2), which would also allow me to adjust the pointing. After installing it, the light's body touches very slightly the front carrier block when I reach the right pointing.

I kinda gave up and decided to mount it on the handlebar with the standard Cateye H34 mount (like the one in picture 3)… until my bike fell while folded and the bracket's tie that goes around the handlebar broke. With the broken bracket in my hand I remembered that I still had some gopro "extender" and maybe I could use the H34 part on that one. Which bringd me to my "solution".

I disassembled the broken mount by removing the screw that attaches H34 piece to the handlebar mount. I attached it to the Gopro extender by sliding the nut in between the 2 flaps of the GoPro extendee and using a slightly-longer screw to fix the H34 piece (picture 4). I squeezed the 2 "arms" of the dynamo light bracket into the other end of the GoPro adapter as in picture 5 and voilà. Now I can adjust the pointing and the light is forward enough to not get even close to the carrier block.

I know it's a very corner case but I still hope it helps someone out there. Stay safe and happy folding!
