Mercedes B Class 2014 Strange situation with Licence plate lights, both lights not working but both check fine with a 9v battery, voltage at LH connection 12v but light will not illuminate!! (I have tried to connect via leads and crocodile clips) voltage at clips measures 12 volts but will not illuminate the light?!I have tried reversing the polarity! Voltage at RH connection 6.5v(?) any ideas? The lights are the LED closed unit variety.
