The idea was simple. Buy a LED rope light, cut it up, power it with batteries, weave it in the spokes, and you've got some sweet rim lights for your bicycle. But it was too easy. The reality was a lot more complicated and it took a while. But the result is a really easy way to add and remove the lights for your bike, and it looks great. Much brighter than other rim lights I've seen.
Here's a look at the lights in motion:
Here how it looks when using the bike:
Step 1: Investigate
I couldn't find any details on how LED rope lights are constructed, so I took the plunge and bought a 12ft. blue one. After I ripped open the package, admired the glow, I decided to take some measurements to see what I was dealing with. I used a multimeter to measure the DC voltage coming out of the converter and got 110VDC. That's when I knew I was in trouble. That's going to take a lot of batteries.
