Interior lights flicker when car is off...why?

Question

I've been noticing this for a while. When the car is off the interior lights flicker a bit. Especially if the car is shaking a little bit such as when people are getting in or getting out.

When the engine is running and the alternator is powering everything, nothing flickers (even if you shake the car). 

I cleaned the battery terminals and posts with a wire brush until I got shiny metal on both the posts and the connectors and made sure that everything was tightened. 

The battery itself is 4 years old but still cranks and starts the engine. It did recently get drained down pretty far (didn't even have enough juice to power the interior lights) but it did take a full night on my trickle charger and fired up again in the morning with no straining and has worked since. 

Could the flickering lights be a sign of a weakening battery that should be replaced soon...or a sign of something else and if so, what?

If there was that much difference in the battery, it would not start the car.  There has to be come corrosion somewhere that can be wired brushed and greased.

Light is a natural form of energy radiated making it visible to the naked eye. Fire was considered to be the first source of light through the mechanism called friction.
