Hi John forgot to add, check the solder blobs on the bottom of the bulb, some bulbs have 2 solder connectors others have only one, look at the old bulb to see which one it is, spare shops will sell both and sometimes get this simple thing mixed up, end result, light still not working!

Could be a duff new bulb, happened to me a few times!, check all the connections by gently moving them with the lights turned on.
