Any idea what may cause a rapidly flashing left turn signal on 05 FLSTN? I replaced the bulb after the first one burned out, it still flashes rapidly as if warning of another issue. Also would like to know options and recommends for replacement fog/aux lamps. Thanks for your time.

 

• is it both left turn signals flashing rapidly?
• have you done anything maybe like turn signal relocation?
• check under the rear fender where the turn signal wires come through the fender.
• wires coming apart under the rear fender are common on this year bike.
• swap your bulbs from left to right and see if the problem switches sides

 

LEDS perhaps? if so, it could be a load equalizer not functioning properly...

 

I'll switch them out and let you know what i find.
