Very cool. I had the exact same thing happen to me, except I ended up buying a new Optima battery that I really didn't need. (Anyone in Eastern PA looking for a battery? )That trunk light killed my battery within 3-5 days. I somehow figured this out when I burned my hand pulling out the bulb which should have only been on for about 5 seconds. That was the only time my car left me stranded, and if I had had good jumper cables instead of the broken cheapies I had, I would have been fine.

Anyway, glad to hear you're back on the road. I keep a DC Voltmeter plugged into my cig lighter so I can keep an eye on my battery voltage. Today I saw 14 volts DC with no accessories, but usually I'm more like 13.4 volts or so. If I use my rear defogger and a couple accessories I drop to about 11 volts. After I shut off the car, I drop to about 12.6 volts, and while glowing i might be at 10.5 volts.
