Number plate lights not working ... Fused?

Hi,wondering if anyone would be able to help.yesterday I decided to change my number plate lights to led.so I unscrewed the lights and removed the original bulbs and replaced the right side with led first,turned the lights on to make sure it worked and it did So i screwed it back in. Done the same with the left one but the bulb wouldnt light up so I thought the bulb must be a dud. I removed the left one and the right one and replaced them both with the original until I get another set of LEDs. Once the original bulbs were back in I tried the lights and none of them are working now, unscrewed and tried the led light that did work before... It doesn't work now. I have no idea what I've done, although I think I may have fused the number plate lights but I'm not sure which fuse is for the number plate lights

Any help would be appreciated
