Those are bright enough for your car? I tried the mini wedge LEDs I have in my license plate, and they are not as bright as the incandescent; and the rated output on them was ~9300mcd which if my memory serves is far bright than the ones you are using. It must be the way they sit in the fixture?
I ended up ordering these for the license plate illumination:
WLED-xHP Specifications and for the marker lights on the front of my xA. I got these for the front marker lights on my wife's xD:
High Power SMD WLED-xHP5 (194 type) 360 degree Wedge Base bulbs Specifications because of where they sit in the reflector.
My big question now is will they be okay with the heat from the main headlight bulb?
Getting the load independent blinker is easy enough -- I'm just wondering if getting brighter units would not have been better:
3 Watt Luxeon 7440/7443 Bulb Specifications
High Power 3-LED 16mm Wedge Bulb Specifications
These are much brighter, but while they have wide angle LEDs, they are narrower than the units I did get:
