I want to replace my sealed headlights on my 1983 300d. I have seen places online that sell Hella E-codes. On the glass lens, I see the E4 code, which makes them ECE lights, but also see "SAE" on the bottom toward the right outside? So, are the Hella E-Codes that are being sold actually E-codes or are they SAE which means they are DOT approved?

I want a true E-Code. Is there a difference between a real E-code and the ones that are being sold online with "SAE" on the lens???

Thanks
