    Computer won't work when Cygolite is turned on.

    Hey fellas,
    When I turn on my Cygolite Metro 300, then my Sigma wireless computer stops working. When I first installed everything, they both worked in unison. Now the computer has decided not to play well with others. Any ideas?

    I had the same exact problem with a Bell wireless computer with the Metro 300 light. I contacted Cygolite and they basically told me to go pound sand. . I replaced the Bell with a Garmin 510 and the interference is gone expensive fix. :/

    The light is great but the wireless interference is a real drag.

    Hey there Buzz...Yep, I can't figure it out. I really don't want to go back to a wired computer. I like the clean look of wireless. The Garmin is an idea though...

    Most decent LED lights use highly efficient switch-mode regulators to control current through the LED. The downside is they generate some spurious radio frequency emissions, which can interfere with wireless cyclometers. Cyclometers that use ANT+ are highly resistant to interference and basically immune to that produced by the LED lights. There are cyclometers that use ANT+ other than Garmin and competing GPS based systems.

    I understand the dilemma. A couple years ago I decided to switch back to a wired computer simply because I knew that I would be using other devices that might either interfere or be interfered with. . Yes a pain to have the wire extending down the fork again but in this case it is a necessity if you want accurate readings on your computer. I chose to deal with a wire again, the lesser of two inconveniences. It helps if your frame or fork is a dark color. Since I have other wired devices on my bike I really don't think about it anymore and my computer I can trust without question.

    Thanks CatMan..I dont want to spend lots so its more cost efficient to go back to a wired unit. My fork is matte black so the wires would blend in.
