Cateye LED light interfering with Cyclometer!

Has anyone ever had problems with LED lights interfering with Wireless Cycle
Computers? I have a Ciclo Master CM408, and when the Cateye led light is on,
the speed will either show zero (0) or fluctuate all over the place, The
other night on the way home, I looked down, and it showed a speed of 53 mph,
and a little later it was zero. This is really going to throw off my
readings! heheheh So much for spending extra bucks on a Cyclometer! Maybe
I should have gotten the $9 buck one from *mart!!! heheheh ;-)

Any suggestions for correction, I am going to try wrapping the LED light
with Tin Foil tonight, to see it it will deflect the signal from the light,
and will update later, but any other advice is welcome.

Thanks, steve

The led light probably has a PWM regulator circuit built in, and it
must be radiating when it switches. Try holding an AM radio near it
while it's on and I bet you'll hear all sorts of neat noises.

You can try shielding it, but I doubt it will help much. The computer
is about at the limit of its range just going from your wheel to the
handlebar. Space the light as far a possible from the computer to
give it a fighting chance. If that doesn't work I'd say you'd better
switch to a wired computer.

Can you mount the light on your helmet?

^^^^^^^^^^^^^^^^
Or how about wrapping the cyclometer in foil?

I wrapped four layers of tin foil around the light, and attached it with a
couple rubber bands! It worked fine last night with no problems. Looks a
little hokey, but at least it works this way. Maybe I can find another piece
of aluminum sheeting that can snap on and off easily enough, to give access
to the batteries..
