my left turn signal will start flashing fast after it flashes normally the first 6 or 7 times. it seeems to go double speed. both thhe front and rear bulbs r working.
his does not happen all the time but it does quite frequently.
any ideas. thanks in advance marcus

 

I have the same problem...Help

 

Loose filament in one of the bulbs. Replace them all and be done with it. Very common on a bike that vibrates like these do.
