OK I had a strange thing happen today. While I was riding I noticed that everytime I would turn my headlight on my cyclometer would start reading 40 MPH or 75 MPH or something crazy to that extent??? It's a wireless computer so the only thing I can figure is that the light is interfering with the computer because it only happens when my light is on

This is very bizarre, I have never had this happen before.

Any thoughts on how to fix this b/c I love my light and really like the wireless computer too.
