Based on some Audi and BMW blogs, I need 25w 10 ohm resistors with aluminum heatsinks.. which seem more expensive than buying new error-free bulbs.
I will check hardware stores for 10 ohm, I'm guessing 25W is the power rating and small ones will overheat. I expect this kind of simple electronics is chinese-cheap sold in packs of 10. But ebay scared me with £3-10 each! Holy...
You know. My google search is full of really, really eager salesmen offering LED CANBUS ERROR FREE XENON NOCANBUS CAN NO BUS NOERROR!!!!! this product is so damn easy to sell and I bet they make 500% profit. It is hard to see actual problem solving.
Hey, nobody talks about this: How about hooking the Halogen lights in the circuit? They would effectively create resistance and do the trick? But where to put the light?
