Default LED turn signal conversion help....

Morning guys, I replaced all my headlight bulbs to LED (except headlights of course). I am loving the increased light output/visibility however, I am getting an error "lamp failure" msg on my display. I've tried 2 sets of LED bulbs of the "error free" variety without success. They don't hyperblink at all, seems they work as they should but I do get the error msg. Anyone have any success with this? What type of bulb did you use? Thanks

Anybody changed out their turn signal bulb to LED? which brand did you use and did you get a lamp failure warning?

Not me, man, but sucks nobody replies.
Maybe you're the first in here to do this?

They blink correctly, no hyperblink but I get a bulb failure warning on my instrument cluster. More of a nuisance than anything else.

My guess is you're either not getting enough current draw, or too much, so the system thinks there's an open or short circuit. The resistor value used in that 'error free' lamp is not right for our cars. Does the manufacturer provide any details on the resistance value? If so, maybe shop for a lamp that provides a higher or lower value (depending on construction of the unit, maybe it can be disassembled to change resistors?).

The bulb monitoring system is extremely sensitive to the resistances of the circuits, to the point where the resistances used on one car would bring faults on another.

You will probably have to add a ballast resistor to each circuit, I had a heap of trouble finding an acceptable resistance when I did the LED rear light conversion on my car, in the end I had different resistances on the indicator circuits left and right.

I'm sure it's got to do with amperage and such. Maybe you'll need to get some inline resistors made specifically to avoid your condition. Evidently the "Error Free" bulbs you have.... aren't.
You didn't perchance get them from Amazon? They have a 100% satisfaction guarantee. Course, third attempt may be just as miserable as the first two.

LED inline resistors @ Amazon

Stupid that you'd need them since you got the right lamps to avoid it.

I bought either these or something similar for the front amber bulb inside the headlight housing to get rid of the Egg Yolk look. They do improve the look and are nice and bright, but they are not LED.

Yup. Similar (although I don't recall the resistance value) to what I used for the rear LED flashers and backup lights in the 'George Kale' installation method.
Use them in parallel with the LED bulb (somewhere in the circuit, doesn't need to be right at the lamp location, just hot lead to ground).
