Bulbs are difficult to judge, sometimes the break in the filament is tiny.
Swop it over to the other side and see if it works there, if not, swop the working bulb to the bad side, just to be sure
Bulb is fine! It's now working on the LH.
I checked the two socket connectors for power (high beam and low beam): both deliver around 12.2V.
Since the bulb and the power and the ground is fine, I suspect the contact in the socket to be faulty. Not sure how to fix that though, it looks just like the others!
