Rev counter bulb replacement?

Would someone be so kind as to post a photo of the rear of the rev counter - my bulb is operating intermittently, so the holder is most likely loose, and I need to know where to put my hand - so to speak

That's perfect - many thanks Julian

Looks more likely to be the plug-in I think. Cheers.
