I notice that at night my white gauge faces have a slight flicker to them. Not a huge deal but anyone else notice this on their car? I'm wondering if it's normal, I should get my battery checked out, if it could be the alternator, ground issue or if I shouldn't worry about it. BTW the car was hooked up to a DieHard Platinum 12V Battery Charger/ Maintainer over the winter and read good. It's the last year of my warranty so I want to get every little insignificant bug out before it's up - ha ha.
