number plate light keeps flashing on the check panel every time i put the lights on ...but both bulbs are fine..any ideas cheers

Takes only a tiny voltage drop to set the telltale off,I have the same issue on one of mine,usualy after crossing a pothole in our wonderful Lincolnshire back roads I expect that the light flickers and that's enough.
You could try another pair of bulbs,good quality one's are better,they cause less voltage drop.
Another possible cause is muck and/or corrosion on the connectors.

check the actual holder is not corroded, clean it with seom emery cloth and bend the holder so they grip the bulb better.

cheers fellas will give it a try

Does sound like an earthing fault - don't forget to clean round the screw holes as the provide the earth.

turned out to be the plastic lens/holder itself ...it was snapped where it holds the terminal superglued it back works fine now......cheers fellas..................clever things these check panels ..even tells you the plastic has snapped
