i absolutely notice a big difference.
the low beams are BI xenons but the eye brow lamp and the turn signals are filaments. the only thing you can change are the eye brow and turns. the side marker is a filament but you need to remove the wheel well finisher to get to that and that was beyond the scope of what i wanted to do.
the filaments are warm/brown tungsten looking--dull. i replaced with 56K LEDs and they look much more elegant on this high dollar car. the fog lamps are much improved as well in terms of looks AND effective brightness on the road.
