This is where the high power ballast resistors come in. They're needed to provide the correct wattage in the indicator circuit the get the flasher to operate correctly. I never managed it without adding large ballasts as well as the LEDs. Seems rather counter-productive somehow.

This is true. I had to use inline resistors for the indicators to appease the canbus. They are simple to fit and cheap. I got mine with the bulbs and they have given no problems. All my other led's have built in resistors and are also fine. Lee.
