Are you sure that the red light is the cause of a battery drain? It would take an awful lot for one small LED to drain the battery.
I suggest a good multimeter to check the source of the problem before calling the LED the culprit.
How long does it take to drain the battery?

It's been 3 weeks since I last started the car, about the same time it took to drain the Mustang. I was still able to unlock the car. It just bugs me to know it is out there blinking away using electricity for no reason. The car is snowed in, and it is snowing again. Come on Spring!!

are you talking about the cars security monitor light? If so, the LED drain from this light is so minimal - it should be the least of your concerns and I'm not aware of anyway you can turn it off.

I have a 2007 coupe that was born on 4/14/07. I had problems with DBS until the dealer did the software upgrade. I thought GM updated the factory software sometime during summer of 07.
If you are hearing a constant clicking sound in the dash, it is a relay that is confused and is causing a drain on battery. My understanding the cause is tied to FOB and relay. Once the upgrade was done, I never heard the continual clicks and no DBS, so far. I have gone over three weeks without starting.

That's just the security indicator for the radio. If someone steals it, it will lock up. Owner's manual explains it. Next to no battery drain from one little LED. But a couple weeks without running, the car will need to be on a battery tender. That blinking light will have nothing to do with a dead battery if if does go dead. It's the systems that remain active such as keyless entry, OnStar... those are what's really contributing to parasitic battery drain. Two weeks or more without running and it will start to go dead.

Having been seriously involved with the original '05 MN6 DBS problem, I can tell you that the little LED lite makes a great DBS detector. DBS refers to previously unexplained '05 MN6 dead batteries that fail in 24-48hrs despite proper shutdown in reverse. This has been found to be due to a glitch in the shutdown sequence, and a BCM software upgrade a few years back has cured the problem. Any other dead battery is either not DBS, or the the car has not had the software reflash. A few early '06's also were included in the reflash.
If that lite is blinking 24-48 hrs after shutdown, you don't have DBS. And that means that your car and battery can now sit for the next 2-4 weeks, depending on the general health of your battery, temperature, etc. When DBS strikes it pulls about an amp/hr from the battery, just as if you did not properly shutdown your '05 MN6.
