Just for clarification...
9004 standard looks JUST LIKE a 9007. The wiring harness is different,
though. Neither looks anything like an H4.
HB2 is the catalog number I've seen for H4-style bulbs. (note same in
your "HB2 DOT 9003 L")
My "credentials" for this: I have one H4 euro and one 9007-equipped
DOT light on my car. Therefore, QED, I've BTDT. :-)
