I keep getting  error code B1121. The manual says that it is a turn signal problem. The manual also says to “replace with correct bulbs”. I am currently running LED’s in the rear turn signals. I am sure that I am not the only one running these LED light bulbs in their motorcycle. Does everyone else get this DTC code and just ignore it? Or do most not know that when the little key light is red it means there is a code?
I have been told that I should put an “isolator”  inline with the LEDs. Can anyone tell me how to do this with a plugin replacement bulb?

TIA, AJ

I thought the key light was only meant for security status and the only codes came from the yellow engine light. Is it possible that the code you received is an old one that hasn't been cleared from when you initially changed the bulbs

Red key light on after engine is started indicates a DTC. Another way to check is to perform a "WOW" check: hold the trip reset button in while switching the ignition to on position.

Thought all LED needed a load equalizer in line.

AJ, think you need a 'load equalizer' as Mr. Magoo stated.  Do your turn signals flash very rapidly (like they would do if you had a burned out bulb)?  LEDs draw so little current that the flasher does not recognize them and thinks you have a burned out bulb.  Not sure how to do this with just plug-in led.  I use the Kuryakyn Panacea system and its controller has a place to plug their load equalizer(s) in - I have two since I run their led turn signals rear & front.

Jerry, this occurs but only occasionally. It does not happen all the time. This is the reason I did not think I needed a load equalizer. Does anyone know where or how to put one in? Any idea of a part number?

A. J.,

Check Custom Dynamics, I bet they have one and probably it's just a plug in into the existing harness.

AJ, here you go:  http://www.customdynamics.com/loadequalizer.htm#Street_Magic_Signal_Stabilizer_(Load_Equalizer)  The first one shown is in fact plug in.

Hard 10 ..... You do need a load equalizer that is alarm compatible to get rid of the problem. What LEDs are you using? If they are Kuryakyn, Kuryakyn makes an alarm compatible plug in load equalizer that should do the trick. I am using it on my 06 FLHTCUSE and I have no problems. It should work with all LEDs, if you have purchased another brand. This unit also has a run, turn, brake converter as part of the package along with the load equalizer.

AJ...Custom Dynamics has a plug and play load equalizer...installs under the seat.  Very easy to install.  Talk to Kristen if she's still there.

The Kuryakyn LED bulbs will not fit into the bullet turn signals. I will have to go and check the actual brand name on them but I know for a fact they are not the Kuryakyans.

I will check out Custom Dynamics for the load equalizer.

My next question is: what happens after I Chief installs the HD LED saddlebag lights. Will they not cause the same problem?

AJ

No.  Adding LEDs on top of normal incandescents still has the normal incandescents (and their load) in place.  Their additional pull is so small they also don't cause any problem from that perspective either.

So then why would adding a set of LED to the rear turn signals be any different? If the front lights are incandescent and the rear are LED would it not be the exact same load?

Because you lost the incandescents in the rear in favor of the LEDs.  That circuit no longer had the load necessary to keep the system thinking it was in tact.  Those four corner's stock bulbs are the baseline.  LEDs in any of them will nearly always make the system think it's got a burned out bulb. 

As long as those four corners are in tact you can add LEDs beyond them.  But if you change them you need the load correction device.

Ok, I understand now...
