DOT Headlight with ECE Lens? (and more Questions)

[AtlBenz]

Does this work or not? Is there a need for me to totally upgrade the entire headlight on my 1994 E420, or is using an ECE lens on a DOT headlight basically the same thing?

How much of a difference is there (can it be quantified) between the DOT headlight and ECE headlight for model years 1994 and 1995. I know that the <1993 W124 DOT headlight SUCK, and as such, the ECE is a huge improvement. Is such an improvement observable with the 1994 headlights?

Is there a need for me to shoot for E500 headlights (with pencil beams), or should I stick with the standard E420 (with fog lights)

I’ve already stated communication with PUMA to get an idea on pricing and availability on the headlights.

Thanks for any help.
