What might this plug attach to? (Rear of fog light globe)

[Columbia]

About to replace the H8 globes/bulbs in the fog light fixture. Looking at the manual, doesn't look difficult.
In the photos in the manual (see attached) there's a plug hanging out, literally, with no indication to what it attaches.
Might anyone be able to enlighten me as to its purpose/function/whatever?
Many thanks.

IIRC, that's the plug for the little optional 'Accent Light' that can go in the pointy front lower/inner corner of each Fog light.

There's a similar optional Accent Light position in the pointy top upper/outer corner of each main headlight too, but if any of those Accent Lights aren't put in at the factory, they're an abso-freakin-lutely painfully difficult thing to get sorted, and you'll need to very carefully and very precisely use a hole saw to cut the necessary hole in the plastic from the rear of the light assembly to slide the light into, preferably also without getting any plastic swarf inside the assembly!
Do you really need to ask me how I know this for such a bloody painful fact?!
