as the title says is this an early sign of my alternator on its way out or battery.

i changed the belts not long ago could this just mean i didnt tighten the alternator belt far enough any help would be great

Are these the lights inside the car? I think Marsdendeans does this sometimes as well, but he thinks it maybe his battery.

check the tightness of the belt mate as that could cause that type of fault..also what else do you have on at the same time?also if you can get a multi meter check the out put of the alternator fully loaded and with no load also check the battery as a bad cell could cause that fault too..
