Apart from that, the remote start system could also help to shut down the engine automatically. This occurs mostly when you engage the brake pedal just to put your vehicle in gear.

That said, you need to understand that remote start systems aren’t always installed alone. Instead, they are usually installed along with an aftermarket alarm. The purpose of the alarm is to help you control various operations when the remote start system starts working.

So, the blue flashing light that you keep seeing near your vehicle’s rear-view mirror is most likely an aftermarket alarm that helps to control the operation of your already-installed remote start system.

However, you need to understand that the blue flashing light near the rear-view mirror could also serve another purpose. According to Drew Peterson, a Quora user, another function of the blue blinking light is that it can be utilized as a dashcam or security camera, helping to record whenever noise/motion is detected.

The bottom line is that the blue flashing light that you keep noticing near your rear-view mirror could serve a couple of functions. First, it could be an aftermarket alarm system that’s installed alongside a remote start system. Apart from that, it could also be that the light is utilized as a dashcam or security camera.
