The 03's have a red surround, and the 04-07 classics have a black surround. With your paint, do the 04-07's. Or you can do like I did and not even put a bulb in there and not worry about the extra blinker bulb.... I am not sure about the circuit not being loaded sufficiently...leaving that bulb out may make it blink fast. Mine doesn't blink fast because I have all LEDs....
