Car light brigthens when put on acceleration

It may be a simple one but can anyone tell me the problem?
Can it be the alternator? I am driving a 850.

I don't know for sure, but I think that's just normal voltage regulator activity - depends on how drastic the difference in light brightness between coasting and accelerating is though.
