I've searched on hear and it seems the consensus was to replace all bulbs when a turn signal is flashing fast. So I did this. Still occurs once in a while after turn signal is on a bit. Previous owner installed LED front turn signals, so I can't replace those bulbs (they are less than a year old). So I've changed both rear bulbs and noticed it happen again, I got off my bike and checked and all signals work properly, just flash quickly. If I cancel signal and restart everything goes back to normal. This only occurs when sitting at a long light, was curious if the auto canceling did this to remind riders to cancel or something. Or maybe could the LED be acting up. As far as I can tell they are flashing, but I'd hate to assume this and have one out at some point without knowing.

Any thoughts?

 

My guess would be a problem with the flasher (if it has one) or the load balancer/equalizer.

 

My guess is the load equalizer is off. Led's in front but not rear probably gonna cause a problem.

 

You probably need a load equalizer. LEDs pull less and can trick your bike into thinking that you have a burnt out bulb. Get with the guys at Custom Dynamics. They will be able to help you. Or you can just switch back to regular bulbs.

 

It sounds like you need a load equalizer.

I'm thinking it might be the load equalizer.

JK.

Thanks for the quick advice! Having a local indy check it out for inspection Wednesday, maybe have him tell me if there's even one installed. When I get home I can snap a shot under the seat, I know there are a couple of modules installed.

 

If you do have one it sounds like it has gone bad. the load equalizer will "equalize" the signal from an LED light which has much less draw than an incandescent bulb so taht it blinks at the proper rate.

My bike has LED tail light (Kuryakyn ) and integrated rear light ..
I had the same thing on and off over the past two years, I stopped thinking of it as a 'problem' but more of a 'feature' of the bike . so looking positiviely I can say this ..

Hey .. look , I got this TwinCam, with Andrews 37's, Doherty Power pacc, and signal lights that sometimes flash quick when left long enough... it rides great .

 

my bike does the same thing, 07 road king. only on the left side, rt side is fine. and bulbs r fine and both lights r flashing just fast after a few seconds.also like above i can turn it off and back on and it starts slow and then goes fast again.

 

YES, my 2010 Road King (with Harley LED's) has started doing this exact thing only on the left. Were you ever able to find a cause/solution?

Thx, Dan
