Guage cluster needles wont light up

All my needles in my guage cluster wont light up since I took it out to paint it because it was gay yellow from when i bought it. Anyone ever have this happen before? Im just gonna tinker with it and see if i can get them to work again…any suggestions would be appreciated

p.s. everything is lighting up and working fine

I think this is contagous… I just caught this today.
