I wish I'd seen this thread a few weeks ago! Just picked up a Sigma Rox 5.0, and I like it. Trouble is (of course) it doesn't play nicely with my new light: NiteRider MiNewt.500 Cordless LED Headlight. Reading through the thread, it looks like the original poster solved the problem by reducing the noise emanating from the cabling connecting the lamp to the battery supply. Given my light is cordless, that's not an option for me. Anyone have any suggestions on how to shield the NiteRider from the Sigma? Or, conversely, any suggestions on alternative lights that play nicely with Sigma wireless computers?

Thanks in advance.
