Let's keep this lens change in perspective. The original change came
about because of broken lenses in the DOT lamps due to Colorado road
rash. ( Maybe it was Canadian or AlCan highway road rash.) The
alternative was a complete assembly at $435, so finding that the euro
lens fit was a stroke of genius. Then, it allowed access to the
interior to clean reflectors and projectors. If you can see through
the exterior lens of a 10 year old light, you will see the haze on the
projector lens. Then the Kansas road rash (Sandstorm) issue was
addressed by also changing those badly pitted and sanded OEM lenses
with the euro lens for less than $50 each.
The idea of changing lenses was economic, not for some superior light
output through the euro lens.
You can look at the lens covers and assume that the lack of fluting on
the euro high beam could result in less focusing from the fresnel
effect, but I don't hear any complaints from daily (or nightly) users,
or the many european drivers. I only saw improvement in the low beam
from cleaning the projector lens and eliminating the light scattering
from the badly pitted lens covers.
I can't illuminate the 9012 area, but lumens don't lie. Now, I can say
HID kits are the best old fart automotive improvement ever made.
Tom, '95 S6, Thats my .02 euro on this.
