2007 SL550 dash lights

Hey Guys,
I have an issue. My dash lights (LED mileage etc) fade from bright to dim. Here's a short video https://www.dropbox.com/s/4jt66u3mk0..._5633.MOV?dl=0
It will go back to bright and then randomly dim. I checked the alternator and battery and they're both good and changing. The battery IS 5 years old - so I was thinking maybe that was the problem. Also, it does the same with headlights on or off. I have it on a CTEK charger when it's not being used.

Has anyone had this issue? I've read where some people will have permanently dim lights but not this.

Thanks for any help in advance.
