So what weight would you put into the beaker?

Is your 09 TSSM turn signal switch and alarm different then my 04 since mine will not function with a LED in the back. It still thinks I have a bad bulb (low resistance and will only work with a resistor added in the line) Do you have a resistor in the line? Know the later model system will work with LED but not sure what year Harley changed it.

10W60 should do the trick.

Has to be a bulb or a short in the bulb wire

My 04 did it, my 12 CVO did it. Every time bulb Shot or bulb vibrated loose.

Leds in back on 04, still when front bulb went out fast blink. Finally got tired of replacing bulbs put leds in front plus load equalizer no issues

So I removed the rear lens cover and all the LED lights work, none burnt out. So I am still looking for a reason. .

Do you have a load equaliser for the rear LEDs? I hooked mine up without a load equalizer. They worked ok for about a week. Then I started getting fast flash. I added an equaliser and all is good. I have since went all LED. I had to add another load equalizer when I changed the fronts over. As already suggested, clean the socket and try a new lamp.

What changed

The turn signals worked fine and then suddenly only the left started acting up.

When I turn on the left side, it blinks normally for about 3, maybe 4 blinks, then goes into fast mode. I removed the front bulb, cleaned off the dielectric grease, checked the bulb using my boat battery to see if it lit, and then put new dielectric grease and reinstalled the bulb.

So other than what I said above, nothing has changed that I can see would cause it to blink so fast.

OBTW, what is a load equalizer? Where does it go, where do you get one? What does it do?

4 way flashers

Searched the forum and found a post that said to turn my 4 way flashers on for 5 minutes, which I just did, but that didn't help either. Still exactly the same.
