This topic fits into several BF.net categories so instead of trying to cross-post it to all the forums where it might be relevent I'm just posting it here in the general forum.
I know many of you have seen the handle bar end plugs with lights built into them. I liked the idea of adding lights to this otherwise unused space but I already have so many lights to turn off and on that adding 2 more toggle switches was not something that interested me. I improved the commercially available designs by automating the triggering mechanism so the lights are on while you are riding and off when you aren't.
The link below contains a video of the lights in action, a parts list, parts descriptions, step-by-step assembly instructions, and lots of pictures of the build process. I'm not selling anything. The information is posted so anyone can use it (non-comercially) to build these lights or modify the design however they want for personal use. Please check it out and let me know what you think.
Thanks in advance for checking it out.
