I will try to explain my problem as clearly as I can...

I purchased a Wisamic LED headlight for my 2011 softail standard. 35w low beam, 50w high beam. With the LED installed I turn the bike on and the red security light on the speedometer stays on permanently. Im sure this is a warning lamp to say one of my globes has blown. Because the LED only draws a low 35w, the computer thinks the headlight has blown. However, when I turn my ignition on and quickly flick the LED to Hi-beam (increasing wattage to stock headlight), the security light doesn’t come on. But as soon as I flick it to low beam it does come on. 

I looked up the Harley fault code for this red warning light on my bike and it is B2113 (accessory output shorted low). Thinking I need a resistor to increase circuit wattage, I did some research and bought a Canbus H4 LED conversion cable.

I finally received the Canbus H4 led conversion cable and after installing it hasn’t solved my problem with my warning light on dash. I’m thinking there is something wrong with the supplied LED light itself and that it is faulty. When I reinstall my original OEM headlight back on the bike the warning light goes away. 

I have tested many things on my bike, and it seems the LED lamp is the only thing which creates a problem. Have I overlooked something here? I want to exchange my LED headlight for a new item, but I don’t want to go through this process only to find I still have this red warning lamp issue with the replacement LED headlight.

1: should I put my own resistor inline rather than using the Canbus one?

2: should I exchange my LED headlamp for another one? 

3: Should I just forget using an LED and just upgrade to a better halogen globe? 

Your opinion is much appreciated. 

 Thanks Tim

Man I searched and searched for an answer.  Maybe the answer has been right in front of my face all along :)

   So i bought a HOG light replacement led. 

   Both these are plug n play. No trouble with any warning lights on dash coming on.  Maybe there is something else you have done to upset it. Or maybe the led headlight you put in, had something wrong with it. And now need dealer to clear codes. The HOG light mob are in Brisbane area, and the Low beam stays on when high beam activated, giving more light directly in fro t of you plus out in front.

Have a look at Yankee forums and your issue is not uncommon but may be potentially tricky to fix on a canbus system bike which your bike is.

I returned the Wisamic and will buy another brand LED, if it persists with the new LED I’ll hard wire in a resistor.  I’ll keep you posted on how it turns out.  

I then purchased a 50w 6ohm resistor and soldered it between the yellow and black wire on the headlight plug and this finally solved my problem. Light works great with no error codes. The resistor is small enough to fit in the headlight housing. The resistor generates a lot of heat and my headlight housing gets very hot, so I’m going to have to reinstall it on the outside of the housing so it can cool off in the breeze.

I hope this info helps someone, as after much searching I could never find the exact answer.

Cheers

Sheesh man. Am not an auto elect"s arseole. 

So I do take heed of your post and thankyou. Myself , I obtained a Chinese copy of brightening the life on bike at night, but, the low beam is fucken shite. High beam good.

Me, being a no money man, went cheap, so, may follow your lead if checks cool and bright..
