How do you check your rear lamp on your bicycle is bright while riding your bicycle at night?. Get a fiber optic cable to run from yor rear lamp to the handle bar to indicate the brightness.
You can also use a fiberoptic cable and lamp to indicate which gear you are in. When a small mirror attached to the gears moves it will illuminate a different fiber for each gear.
A fiber optic cable wrapped around the frame with a cracked outer cover will light up your bicycle.-- pete anderson, Mar 25 2001 Glowire http://www.glowire.com/I nabbed this link from Jutta's 'Broomcycle' idea. [StarChaser, Mar 25 2001] Welcome to the Halfbakery! Good idea - there should be more fibre-optics on bicycles-- hippo, Mar 25 2021 //Welcome to the Halfbakery!// I hope that's not been on your to-do list these last 20 years, you'll be running out of things to do at this rate.-- zen_tom, Mar 25 2021 There are a *lot* of things on my to-do list-- hippo, Mar 25 2021 random, halfbakery
