The only lights that flash for the turn signals on the mirror housing are the LED strip on the front of the mirror which is not visible to you while driving.
Yeah, sounds like the OP meant the Blind Spot Detection system.
Those Amber Triangles will light up if:
- You active your turn signal to the left or right AND
there is a vehicle on that side of your vehicle, possibly in your "Blind Spot". It is a safety feature and only activates when you are about to change lanes into another vehicle.
