Colour wise they are the same.
On my old dynamique I had factory fitted Xenons which were the same as what they put on the 182's.
Comparing these to the ones on my 197, the 197 ones seem very slightly better. The ones on the dynamique were brilliant dont get me wrong, hence why I wouldn't really consider buying a car without them after that but the way the 197 lights shine, they just seem to give a better spread. Heck it could just be that the seating position is different or the lights are physically higher on the car or something but the illumination just seems to be improved.
Also on the 197 when you switch them on, it seems like every other time they're switched on they move up and down like what I've seem them do on a BMW. I believe this is to stop the auto levelers from seizing. This never happend on my dynamique.
