For headlights with free-form multisurface (non parabolic) reflectors, it's difficult to get the required precision from a stamped metal reflector. In this type light the reflector is handling all the photometrics to generate the beam pattern; the lens is unfluted and clear and serves only as protection for the reflector. With a parabolic reflector with a fluted lens, the lens determines the beam pattern and the only thing the reflector is required to do is focus the light source at a certain point on the lens.
Here is a picture of one the Autopal standard E-code headlights. Look closely on the lens and you'll see the E4 indicating it is a Euro-code approved headlight. The clear lens light he sent me had no E-code markings on the lens, even though the auction said it was E-code approved.

"E-code" simply mean a headlight that meets current European specs for light output and beam pattern. An E-code beam pattern has a very sharp horizontal light/dark cut off with a sharp rise to the right (or left, if you're in England).

These are "replicas" of the old Cibie Z-Beam headlights. These are not marked as E-code, but I have a distinct memory of what the lens on my Z-Beams looked like, and this is it. So the beam pattern will have a sharp cut off, but no rise to the right like an E-Code would. (In fact, that was the main difference between a Cibie E-Code and Z-Beam: the sharp rise to the right of the beam pattern on the E-Code lamp.)

Gary, sorry to hear about the bad experience. I bought mine from the same seller too, rimiinc.

Quick memo for FXDF owners thinking about this mod. If you have the FXDF quick detach harley windshield, it won't fit after installing the headlight. DOH!
It would need to have a curve cut into it to clear the bucket. Or a custom headlight mounting block to push the headlight out farther. Oh well, i guess it's time for a windvest for me.
