Like another user mentioned, the reason you're seeing errors is because the bulbs respond to fluctuations in current differently than incandescent bulbs.
You may have noticed some "flashing" when the car was first turned on. That is one of the two kinds of bulb checks that the car performs, either hot or warm. I'm a little out of practice (I'm at school away from my car) but one of the two tests to see if a bulb is burnt out, and the other tests to see if there is a bulb in the socket.
I'm not sure why you're still getting errors though, I bet clearing the error codes with INPA will clear it right up though.
