Bulb is fine! I checked the two socket connectors for power (high beam and low beam): both deliver around 12.2V....I suspect the contact in the socket to be faulty. Not sure how to fix that though, it looks just like the other...
odd, if you have voltage. Maybe a loose contact, broken wire, that just happened to work when you tested it? Tried wobbling it about, moving the wires with the headlight connected and power to lowbeams on?
you can find new H4 connectors (H4 Steckkupplung) for a few euros if need be.
