This is an odd one. I recently installed a Planet Bike Blaze 1W light on my handlebar next to my Trek Incite 8i wireless speedo. They are about 4 inches apart. When I turn on the light the speedo jumps up +/-40mph until I turn off the light. I'm guessing they're working on similar frequencies or something like that but am wondering if there's anything anyone else has tried to solve this beyond switching out the light or the speedo? Also, if I switch out the light are there others I should avoid so I don't duplicate the problem?
