something electrical going bad??

So umm....this might always have happened, but since I got the car, I noticed that if you are trying to put two windows up at the same time, the windows go a lot more slowly then if you are trying to put up just one at a time. That never bothered me, it just kind of made sense. But then last night, I noticed that when I tried to put two windows up, or even one window, that my head lights and my cluster lights dimmed. Not drastically, but they definitely dimmed.

Is this normal, and has it just...always happened and I never noticed it?

Thanks.

very normal... more electrical load wears on the total system... if you put more things in a shopping bag will it make you have to lift with a little more force?
