Yeah, the lights dim as the voltage goes steadily downward.
It stopped running tonight. I had to push it into an HEB parking lot to try to fix it. It took me two hours(1 hour without tools) to figure out that it wasn't my battery. Igovert was right, its the alternator. Just by dumb luck I happened to run into a guy who worked on my car with its previous owner, and he said that that was the one thing that they didn't fix. So it'll be towed to a shop tomorrow. And will end up being sold within the next couple of months so I can get my VR-4. At least I'll have two turbo's...
