Lights Flickering at Speed

[Nati0nalxCrisis]

So I've got a quick question.

I don't have a DSM but I would imagine the problem would be related to any vehicle.

I've searched but I can't find anything really related to the problem that I'm having.


When driving about 50 miles an hour my lights tend to dim then brighten back up to normal, dim again then brighten. This happens steadily, like constantly, almost like I have subs and no capacitor. Funny thing is, I have no sound system, I actually only have front speakers .

I also noticed that before it started happening I could get it to flicker like this when I had my window rolled up and I hit the up button, hitting the button would cause them to brighten/dim.

All of this leads me to think somethings up with the alternator, all my fuses are good.

Help?

sounds like the altenator to me, but if they can dim by just hitting the window switch sounds like your battery is weak too. Try and put a volt meter or gauge in and check it out under the conditions that the problem is happening

Hmm I'm not sure if it could be the battery at all though, the battery is actually only a few months old. Ill check it though when I get out of school, any other ideas?
