If you want to get the Silverstars, make sure they are made by OSRAM, and not Sylvania.
But if it were me I'd ditch the whole NAM setup and go with Euros, then drop in a set of respectable H4's. Personally I use OSRAM Night Breaker Plus in my 190E and they got superseded so they are now Unlimited, I have them on my 300D.
Old Nightbreaker "Plus" in my 300D - notice the faded blue coating. New ones obviously have unfaded blue coating similar to old one. Low beam has NO tint (clear band). High beam has the blue coating.
"Plus" (old)
"Unlimited" (new)
"Made in Germany"
But that's just me
