Random extra light. Foglight?
This ones been puzzling me for a long time now and was wondering if anyone else knows has seen one. The picture is not very good but I am talking about the light to the left of the normal light unit. It takes the same bulb as the brake light if I remember correctly.

The light on the dash that activates it has a foglight symbol on it. However I have never seen one on another D*lly (or Special or Charleston for that matter). Every other 2CV I have seen has the foglight attached to the bumper, and as I have heard often gets knocked off. When I took it down to get its pre-MOT check at the 2CV guy, he said that Donna would likely fail its MOT for not having a foglight (and need of welding and suspension, but thats another story!).
So, any ideas?
