That little red light blinking on your Nissan's dashboard or near the stereo is the security indicator light. It's a simple deterrent, meant to make a potential thief think twice before messing with your car. When you lock the doors with the key fob, it starts flashing to show the alarm system is armed. If you ever see it solid or acting weird, it might mean a sensor is off or the battery in your fob is getting low.
