Ok so I changed the bulb. However, the problem persists.

Sometimes all indicators work and then sometimes the front left one that I thought had broken, doesnt and the other lighter flash fast. Sometimes it doesnt work and the other lights DONT flash fast.

So I know pretty much nothing about electrics but I am willing to try and figure out. Anyone have an idea where to start looking for a problem?

Like I said the bike is pretty new, 2013 model with 7800km on the clock so I am a bit bummed that I already seem to be having an electrical problem. I hope its something minor.
So yeah, any suggestions?
