My Ride: 2000 BMW 328i
Unhappy Dim Lights...Help!!

I have a 2000 328i sedan, and just tonight I noticed my headlights dim to almost off then shoot right back up. If I give it gas till about 2500 rpm then take my foot off the gas it drops back to normal idle but right when it hits idle rpm my lights go almost off....like I said before, then go right back up. Not just the headlights, all interior lights do the same. This not only happens when I let go of the gas but then also when I hit the button to roll the windows up, the lights dim. Never seen this before any ideas???
