The small orange indicator repeater lamp is not working on my driver's side wing mirror. Am I correct in assuming this is an led? Any thoughts on replacement/access would be greatly appreciated. I realise that this may not be a bulb issue, but it seems reasonable to investigate this option to start with.

Might just be a bulb. 

Isn’t it funny we still call them wing mirrors ? … i myself still do 

Ha – I don't know what else to call them!

Side mirrors. But we all call them wing mirrors. 

Hi Jason, thanks.

The bulb-out sign is showing; everything else seems normal. What I'm not clear about is whether this is a simple bulb replacement or whether the bulb is integral to the whole curved light unit.

Many thanks. I may have to come back on this as I'm away from home at present, without the car. I know it was 2009, B7, A4 Avant 1.0 TDI.
