The C0281 is for the brake light. The C0561 code means that there is a problem with the brake system, which could the same brake light. It's possible that the codes are not related to the current problem, the code more than likely were set when the taillight was damaged. Try clearing the codes and try disconnecting the car battery for about 30 min, to reset all the systems.
