re: "...That is why I switched lenses to E codes, a much better light pattern...."

I wholeheartedly agree: since the early 1970's, I've used Cibie e-codes in my "sealed-beam" designed cars; and since more-recently owning non-sealed beam-styled cars (i.e., my '93 240s) I've also promptly spent the high costs of putting in Euroheadlights. I just can't feel safe at night (driving as I do in suburban/rural roads) without their assymetrical low-beam cutoffs. But don't fail to acknowledge the superiority of these lamps' high-beams, too! They're extraordinary even with mere 55/60W H4s* compared to any sealed beams, and living where I do**, I have ample opportunity to use them properly. :-)

[ * On my wife's car (with Euroheadlights) as well as all my earlier cars with e-codes, I've only used ordinary 55/60 H4s -- they're more than adequate. But on my own car (also with Euros) now, I've finally upgraded to using 80/100 H4s with 10 gauge wiring and relays -- a bit overkill, but since I drive a bit faster than my wife, a bit more reassuring on our local roads.]
[ ** with many dead deer (and other wildlife) strewn along the roads as ample proof of the dangers here. Thus, my inclination to suggest using high beams wereever and whenever feasible to provide earlier warning of what's farther ahead.]

Best regards,
