In the US E-code are technically illegal. What we get ar DOT/ECE (harmonized) hybrid so to speak. G-man DOT HID actually has a right hand flare, it's different from the E-code flare.
DOT (HID) looks like __|--- __|-- or usually has a Z step, whereas
e-code usually looks like __/-- __/-- or a slant step. E-codes typically put out more light, but has a sharper contrast from light to dark, and no light kick up to light up overhead signs. DOT still requires light kick-up, the harmonized projectors are pretty darn close now compared to past projectors. Typically Stanley/Koito have some of the highest output as far as projectors, and can be found on the AP1 & AP2 S2000 (Wide and bright). ZKW's are good but difficult to find, excep on a few BMW models.
