Odd bulb behaviour

[mini1380cc]

The lights have been working fine up until today.

First click on the rocker switch and all is well, the side lights come on.

Second click for headlights the near side headlight and sidelight come on as supposed to but the offside headlight bulb appears to be out AND the sidelight goes out. On top of this the blue full beam light on the dash comes on which I think should only come on for full beam. Toggling the stalk back and forth doesn't put out the light but does still successfully switch the one working headlight to full beam.

The headlight could simply be out, but why would the side light go out with it? And what is up with the full beam indicator?

Almost certainly an earthing fault

This was it. The connectors under the slam panel were corroded. All good now.
