what's this blinking light?

A photo would no doubt help, but it's too dark.  I'll get one in the am if needed.

I've only owned my 2003 LS430 a couple of months, so I am still learning things,  I went out into the garage tonight and noticed that there is a blinking red light, a tiny dot, on the surround of the section that contains the rpm dial, speedometer, etc,  It is just under a drawing of a car.  It's on the left side of the surround.  The owner's manual doesn't seem to show this anywhere.  Any clue as to what it is trying to tell me?  Thanks.

If it is the little light to the left of the instrument panel rheostat knob, it is the security system indicator light.  See pages vii and 178 of your 2003 LS430 owners manual which you can also view at and download from https://drivers.lexus.com/t3Portal/document/om-s/OM50647U/pdf/OM50647U.pdf

I've always that it odd that this light blinked regardless of whether or not the car is locked.
