Hi to you from David, 'The Famous Forry'
If it is wired right as you say , then the bulb/s are in need of changing or the fitting is at fault. Are/is the bulb/s ok.?
Return the fitting for one that works
Sorry part of that answer has not come through
It should have read, Return fitting for new one if your 100% it is wired correctly or upload picture of the wiring so i may help you further
