Bit of a strange one. When i switch on the left hand indicator, it will flash at the normal rate, then suddenly flash very fast, then back to normal rate again. My first thought was that one of the bulbs had gone but that's not the case. I spent 15 mins today checking all lights and i can't find an obvious cause. Reading the manual (and from my K100 experiences) the rapid flashing should only occur when a bulb has blown. Anyone seen this quirk before?
