I just got a 2019 XC90 and drove it home.

when I parked at night, I noticed flashing from under/behind the front left tire. It was blinking white and green LEDs then finally stabilized as a solid green.

anyone know what this is? Should it be doing that?

 

That's something aftermarket - it's cable tied on - how about a GPS sensor so the Buy here/Pay here used car lot can find the car when it's time to be repossessed? Who are you making payments to? ( I would disconnect that)
