What is the purpose of the rear anti-fog lights of a passenger car?

aThey increase the effectiveness of signalling the fact of braking in fog.
bThey replace position lights.
cThey improve the visibility of the car in fog.
Why?
The bright red lower lamp in the picture is a rear fog light, which makes the vehicle easier for following drivers to see. It may be used when visibility falls below 50 m and must be switched off promptly when visibility improves. It does not signal braking or replace the rear position lights.
