- Bulbs are halogens. They are the kind where you have both the low and the high beam contained within the same actual bulb itself. When you look at the bulbs in a cursory fashion, they don't look particularly bad. But when you look very close, you can see the difference between the highbeam filament which looks fine, and the low beam filament which looks blobby and slightly melty (but not blackend per se).


Tony, dig out an ohm metre and check for continuity across the low beam filament.
(can one do this with halogen bulbs?)
If it's really burned out, there shouldn't be any conductance there at all.
