I suspect using LEDs for indicators is more complicated than expected. I don't think it's the same as swapping a side light filament bulb for a CAN-bus LED. Indicators are typically controlled by the power demand of the bulb, which fixes the flashing rate. Even with an electronic flasher module, I think the same holds true. 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.
