Hi.
The high level brake light on my 03 ff sometimes only has half of the led's working,
sometimes all of them, sometimes none of them (current configuration). Is this going to be
just a replacement unit job or is there something deeper in the ff's brain that could be causing
the problem? QUID FACIUM TIBI

Are the LEDs in series? That could cause problems if some are on their way out. Can you get a new light with a good return policy? That way, if you plug it in and all is good - GREAT. If not, the problem lies elsewhere and just return the new light.
Good luck.
