It doesn't have to be much, there's a 168 hours in a week, so a 200-300 mA drain will flatten your battery in about that amount of time. To narrow down the search put an ammeter in series with the negative terminal lead from the battery and the battery post. Hopefully you will see a significant current drain. If you do, pull the fuses one by one until the drain goes away (or at least seriously reduces) if you are lucky you will find one massive source of leakage and not 5 smaller ones!

However, if you turn on the hazard lights, this dim still happens... but it's not nearly as profound. I would think that having both sets of blinkers on would draw more power, but apparently not.

There would appear to be a high resistance somewhere causing a voltage drop, possibly in the indicator switch itself or associated wiring, but the hazard warning system and the indicators do use separate fuses, so the problem could just be a poor contact at the fuse. Use a meter on the volts range to find where the voltage drop is occurring.

That's definitely wrong. No clock takes over 10 amps! But seeing as the clock circuit is powered all the time, I'd suspect that the aftermarket security system tapped into this supply and the additional redundant wiring is occasionally shorting out somewhere.
