What is this Red light indicator?

A picture of the light would be most helpful.

If I had to guess though it would be an LED for an aftermarket alarm system
 
Yeah, sorry. Can*t seem to get the pic uploaded. But it does look like an aftermarket led light. The alarm will go off every few minutes or so for about 3 seconds when I first turn the car on. Battery has been getting low also.
