With regard to the Canbus bulb failure warning, I'm interested to know how this works.
Does the system look for a certain resistance, or does it look for a certain "minimum" resistance?
I plan to install LED sidelight bulbs, and also tap some DRL's into the circuit. I'll measure the resistance of the original bulb, and the LED's and get a resistor as close to the difference as possible.
How accurate do I need to be? I don't want to be too far over the resistance of the standard bulb due to heat, but how accurate do I need to be?
That is of course assuming it's only resistance that is monitored.
