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.
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.
