This Instructable will teach you step-by-step how to integrate automatically illuminating LED's into the ends of your bicycle's handlebars.
The lights operate using a reed switch and magnet so very little permanent modification of the stock handlebars is required. The only irreversible alteration required for this project is holes for the lights drilled into the handlebar end plugs. This modification can be done to any bicycle in an afternoon using only basic hand and power tools. If you decide to do this modification to your bike please take some pictures and I will post them here.
There are two main groups of people who I think could benefit from these lights. The first group is comprised of anyone who owns a bicycle. Much like books are great for people who can read, and cars are purchased most frequently by people who can drive; these lights are perfect for the bicycle owners of the world.
The second group of people who could benefit from these lights would be people who do not own bicycles. I know what you are thinking, "Without a bicycle where would they put the lights?"
I thought of that too. The best solution I could come up with is that people in this second group should buy bicycles and join the popular kids in group one. As writer Iris Murdoch once wrote, "The bicycle is the most civilized conveyance known to man. Other forms of transport grow daily more nightmarish. Only the bicycle remains pure in heart."
The scope of this instructable is limited to bicycles with mountain bike style handlebars. This system could be easily adapted for road style "dropped" bars or even motorcycles but in an effort to maintain focus; those areas will not be explored in this guide.
