H4 is the bulb. E-code is the European certification for the lens
pattern. In the US, DOT specifies certain parameters of the beam
pattern, which we all know and love *cough*. A lamp that is E-code
certified, but not DOT certified, will have a much nicer light pattern,
including that sharp cutoff you like. You'll know them when you see
them, as if you're approaching a car with them, they won't look very
bright, but that's because they're putting the light where it should go,
rather than in the oncoming drivers' faces.
