​What’s the purpose of this band-like tag on the headlight of what looks like a very new car? Seen in the US.

What is the purpose of this tag? Looks like a stick on tag with strip for possibly scanning. Seen on the headlight of a Porsche Cayenne SUV parked in the neighborhood. Only on the front driver headlight.

Photo is edited to remove my reflection and a long number seen on the tag.
