Beeping when using parking brake

I like having it. I have an auto, so I rarely use the parking brake, except when I am I am off road and parking on hills, or off camber, having witnessed one TJ take off down a hill in park. (driver was careless and didn't come to a complete stop and let the sprag fully engage, but still, better safe than sorry) If I am in 4 low and put the Jeep in drive, it only takes a little throttle to overpower the parking brake, and I always forget I have it set. The beeper is nice for that.
 
BAD !

test done:
- stop my vehicle
- keep my foot on the brake pedal
- pull the hand brake
- Beep beep beep beep beep beep (five times)
