It's not the high beam as that is part of the bi-xenon (as DeerHunter mentioned). That was easily tested and the xenons get brighter and these bulbs don't light up when you turn on the brights or flash them.

It's not the fog lights as the fog light switch doesn't turn them on and per the manual the fog light switch is for the 'rear fog lights'. And it does turn on the rear fog lights.

As DeerHunter mentioned, it may be a cornering lamp, but after researching/testing I suspect that's part of the 'Adaptive xenon plus headlights' (which are only available on the Prestige). It is mentioned briefly/vaugely in the manual to turn on the Adaptive lighting in the MMI and with the light switch in 'auto' you would have conering lamps. But I don't have that option in the MMI. Also, I tried to get them to turn on with the turn signals or just by turning the steering wheel...I have tested both of these with the car in motion and someone watching, those bulbs don't come on.

I'm open to any and all ideas...thanks!

To tenspeed...it already has bulbs from the factory (came that way).

Here in the US I'm thinking that MacA7 is correct...it's for nothing.

Sorry to say, but I think thats the answer?!
