I've installed a LED headlight on my 2011 Fatboy Lo and it's now throwing a error b2136 and the red light on the speedometer is on. I ran a search and see that others have had the same problem but I couldn't find how they fixed it. It seems to have to do with the bike thinking the bulb is out due to the low voltage of the LED. Has someone out there figured out a way to remedy the issue?

 

I have an led headlight with no such problem, but my product of choice probably utilizes a load equalizer internally. You may just need an external one.
