What is this connector for?

[Af8]

I noticed these connectors by each headlight. Per wiring diagram for red/white and Brown/white it’s a hot and ground but there is no reference in the manual what these plugs are for? Any ideas?

I think it’s daytime running.

Here’s mine

Lights off

Lights on

Should be keyed
