If as GP said the bulb fault is sensed as resistance is too low, putting a resistor in parallel with the LED will reduce the resistance even further.
I think it's the I^2R loss in a (series) resistor that makes using a resistor problematic from the POV of energy savings.
- tyingq 7y agoThe sensor is looking at current draw. If it's too low, it assumes a burned out incandescent. Basically, the LEDs are too efficient and look like a burned bulb. The resistor in parallel draws enough current to make it happy.

- taneq 7y agoThe reason you need the resistor is that the LEDs pull too little current, not that the voltage drop across them is too low.
