The usual fix is a resistor in parallel with the bulb, mounted externally to the shell to avoid cooking things in there as it will get very hot. One per bulb.
You could always try one of the Auxito bulbs referred to in this thread.

I’ve been riding almost every day, and no issues after I replaced the low beam bulb that gave me an error.

Any idea on what ohm register to ue
The stock bulb is 55W so you’ll want something that will bring the total current up to something like that. At a guess, current to serve 45W would be over the trigger point for the chassis computer to not cause an error.
You’ll need to measure what your LED draws and use the following formula.
R=V/I

Yes, it was working fine. No visible damage of any kind, bulb still worked even when it gave me an error on the dash.

I have to wonder if the errors are coming due to temperature. If the light is controlled with PWM with temp feedback the width of the light off pulses could go up when things get too hot. My initial error with no resistor installed didn't show up until I was sitting still in heavy traffic. On the other hand this could be complete nonsense since it's a mechanical engineer hypothesizing about things electronic :)

Based on my original testing, fan accounts for good percentage of the total load. I believe fan was getting stuck on my defective bulb, and was able to spin-up periodically. Depending on the circuitry used, it is possible that bulb recognized fan not being able to spin and cut the load associated with it. It would explain why the error was going in and out as well, in case if the bulb was periodically trying to power-up the fan.

That would make sense.
