Was just trying to help everyone out, as the seat post mounting of the light was not practical due to the leg hitting it, like yourself I didn't like all the extra cable floating around.

I think there won't be any problems with the heat, you can use a thinner velcro strip to expose more of the light head body, I think the only potential issue with the light is the weather proofness of the battery housing but you could solve this by putting a balloon around the battery pack and connector and use its case.

The velcro strip I am using has a D-link sewn into it. The velcro first goes through the battery pack loop then the O ring, the end of the strap with the D-link then wraps around the saddle rails and pulls the pack and light up into the seat, the other end of the strap then gets passed through the D-link and everything is cinched up tight, it then wraps around the underneath the light to the other side where it sticks to itself. This method keeps everything secure, the light is held twice by the strap through the O ring and the strap wrapping underneath it.

This shows the strap through the battery pack loop and the O ring.


This shows it all wrapped up, D-link on left, strap across the top goes over the saddles rails.
