I would have to think, IMO that the dual-intensity circuit was made specifically for the LED side markers and not the incandescent bulbs.
What that tells me is the diode just needs to be changed. It's my understanding that AAC gets those dual-intensity circuits from an outside vendor, so conceivably that vendor may have a version of the dual-intensity circuit that will work flawlessly with the factory sidemarkers. I suppose that would just take a little extra research on yours or AAC's part...
