Awhile back I wrote about Reelights. While they pretty much work as advertised, I've discovered one interesting incompatibility; the front Reelight conflicts with the bike racks at the Seattle Bike Station where I work.
At first I noticed that the light would bonk into the rack when I'd park. Sometimes it would get knocked out of alignment enough that it would be moved too far away from the wheel magnets to blink. Later, I noticed that the light started making a ticking noise every time the magnets would move past it. I surmised that the jarring knocked the inner coil loose. The ticking was the coil shifting each time the magnets tugged at it.
Eventually I parked one too many times and I broke the front light. The case popped open and the internal parts fell out. The good news is that I got some pictures.
The coil attaches to the circuit board with incredibly tiny wires. I don't think I'm going to bother with reassembling the circuit and I'm going back to using a front LED light powered by rechargeable NiMH batteries.
