Humm, I'm not sure to be honest. I haven't noticed warm white ones, just the stupid blue things which are round and in the sides of the footwell trim, there is a small on off button under the steering wheel trim, although it doesn't seem to be all off when its off.... Maybe they have swapped the standard ones for blue, but not hopeful. Hopefully over Christmas I will have the time to look around the beast properly, and read the manual.
I didn't realise there was an indicator stalk with fogs on, that's a good shout, mine had a generic fog switch fitted to one of the blanks, I ordered a proper fit fog switch for the blank, but haven't fitted it yet.
As it seems like I might be popping a fair bit of trim for this and that, I have put a set of trim removal tools on my Xmas list have a tow bar to fit before I go LPG and I want to swap the 100v stuff for something useful.
I cant remember how my fog light has been done, it works, and nothing horrific externally to see, but I appreciate the info. I do hope they haven't drilled into the back of a reflector.
