Water spots in speedometer lens

[Polemonkey]

Hi all, I have a 99 Royal with the speedo on the tank, and have some what looks like water spots on the inside of the lens(condensation?). I took off the crome trim and removed the speedo but best I can tell the trim on speedo itself is crimp sealed, anyone had the same problem/fix, not a big deal but in certain sunlight it puts shadows on speedo face and is annoying, Mike.
