Cateye computer killed by LED light
I have a Cateye wireless computer mounted on my road bike, I was so impressed with the unit that I treated myself to one for the Trek Y22 mountain bike.
After installation the unit worked fine, but then it started to not register MPH, the unit would wake up when you started moving, the clock would start but that was it.
The main issue was the problem was intermittent with sometimes the MPH working and then stopping again.
I adjusted the unit so the wheel magnet was in the correct position, moved the sensor forward a bit but this had no real effect on performance, still intermittent.
Then riding home last night I noticed the computer was working, the light was getting low so I turned on my Hope Vision lights, the next thing I noticed the computer had stopped, I turned off the lights, computer starts....
I turned on my secondary front light, a cheap Cateye unit and had no issues.
So it seems that high powered LED lights will help kill off your cycle computer, I need to move the Hope lights further along the bars to see if the interference stops. Either that or purchase a wired computer system.

I was searching on this exact same issue when I came across your blog. I have a Blackburn X6 system and use a Sigma BC2006MHR wireless computer on both a road and mountain bike. I have the same issue. I moved the lights away as much as 5 inches, and the lights still interfered with my computer syncing with the wheel sensor, so it's not just Cateye or Hope. I wrote Sigma and was told this was a problem with nearly all high-powered bike lighting systems and that Sigma (of course) would soon be releasing a light that did not interfere with their bike computers. For not, I have purchased a second computer mount for both of my bikes and stuck them on the top tubes. This seems to have solved the problem for now.

Thanks for the feed back, I am glad its not just me that is having the issue, I will try some new mounts on mine to see if that cures it as well.
