Iv been meaning to get around this problem recently, but only got the chance today. The background lights went off on my MFD about a month ago.(very annoying)
I took it off today and checked the three screw in bulbs, and they seemed to be fine?
I was hoping to find them blown? what are the chances of three of them blowing the same time? shall i replace all three? or is there another problem i need to look at?
Are these bulbs a pug part?
Any help appreciated

Pete
