The problem with the '04 - '06 is that it doesn't have 2 filaments like the pre-facelift model. There is no 2nd filament to make the blinker function brighter. The blinker will only turn the bulb on and off (not brighter), even when the parking lights are on. If you paint the bulb to hide the light output for the parking light, you will also take out the blinker as well. That is why it is so difficult on a facelift model, which I don't think can be accomplish without a reprogram.
