Blinking Blue Led When Vehicle Is Armed/locked

[Invinzor]

Hi,

There is this blue LED located somewhere on the rear view mirror assembly that flashes whenever I would arm/lock my RX350. This is clearly visible especially at night or inside my garage.

I noticed that it stopped flashing today.

I can't think of anything I did that would cause the change in behavior.

Can someone confirm if tis blue LED is in fact related to arming.locking the vehicle? As well, what could have caused it to stop flashing now?

Thanks!
