While riding my '03 FLHT, I noticed that my left hand signal indicator was intermittently
flashing. The indicator light would flash for a number of seconds, (10-15), then cycle off.
After about 30 seconds the cycle would repeat itself.
I was riding while this was happening and don't know if the signal lights where lighting as well.
After stopping the bike; I checked the signal lights all where working.
Is this an alarm indication and if it was; any thoughts on what might be causing the alarm?
The indicator light "flashed" for about 4-6 times, paused for a couple of seconds then flashed again during the 10-15 second "cycle".

Thanks for the help.
