Unknown Use Of Button

[BigStag21]

I have an 05 reg C3 LX Mk1 and there is a button that is on the end of the indicator latch. What is the purpose of this anyone? :)

Welcome to the forum.

 

We had a 2003 C3 and I vaguely remember that button did not do anything. If you have the car handbook it may say different. On a 2004 C5 I think that button was used to set the auto headlights on or off. If you have auto lights then you will also have a light sensor at the top of the inside of the windscreen.
