licence plate bulbs on 56 plate superb

[MICKEYMAC]

HI

I have decided to change the lights on my car to led (canbus no errors from e bay)

mainly because the contacts on my old lights were broken, and led were as cheap as new units. problem i have is that I fitted one, and it worked fine, (drivers side ) fitted second one and then both of them went out, like a fuse had blown etc, checked fuse box, cant see fuse blown , the lights themselves are fine(as i checked with cable and connected to battery, guess my next route is check for power again on both units, using multimeter .. are there any other fuses anywhere that might have blown, as i heard a pop ..

cannot use old lamps as they are beyond use

any ideas
