I cannot find a relay for the low beam bulbs at all. I just made a new
discovery though: the positive side of the low-beam fuse sockets are live,
even when the lights are switched off. I guess this means the power from
the battery goes directly to the fuse box, and then after going through a
fuse, the feed goes to the headlight switch before going on to the light
bulb. This means it could be the headlight switch that's caput, doesn't
it? That's assuming that there is two separate contacts inside the
headlight switch - one for each bulb. If there is only one contact, then
the break in the circuit must be elsewhere.

Are you able to see my posts?

I ask because you have already been told that if you have no daytime running
lights, then there are no relays for the headlights.

I would be amazed if any car maker would provide separate contacts, which
would also mean extra wiring, for each individual bulb.

If you are *sure* the bulb is OK, and you are *sure* there is no voltage
reaching the bulb, in the absence of a wiring diagram your only option is to
physically trace the loom back to wherever it connects to, and test there.
