Nope, standard headlights, and none of the other lights (internal or external) are flickering as I've read about with earth problems. It's probably just on its way out
I thought the wear indicators had a separate light on the dash next to the ABS one? I'm going to drop in to Kwik Fit or somewhere for one of their free brake checks, as when this started happening it occurred to me that I don't think I've had new pads fitted in the 40,000 miles I've had the car and I got no history of receipts with it when I bought it so I don't actually know how long the current setup's been installed :|. How long do brake pads normally last?
I don't know what a NIME controller is, so I'll assume I don't have one!
edit - a quick google later and I've got
http://www.nime.co.uk/content.php?mk4fans which I assume is what you mean? I'm pretty sure I don't have one installed, at least I've never had one. I suppose it's possible that the first owner had it done in the first 3 years/60,000 miles though.
