R54 2016 clubman brake lights

[McGraw]

Hello

Right rear light has gone out so I bought a replacement pw24w which didn’t work and now the bulb that did work on the left isn’t working after having been tried on the right.

My brake lights are at the bottom and I don’t even know what the ones next to it are supposed to be. Nothing seems to light them up

Any likely cause for this? I’m hoping it’s the light holders somehow

Thanks

Sorted. I wasn’t tightening the housing enough
