Hi Gents, the headlamps started playing up on my AE86 the other day.

when I flick the knob to headlights on, the headlights don;t come on, however my instrument cluster High Beam indicator is on.

Pulling the high beam lever works fine, as do the parkers.

First thought is it's the switch, and perhaps something broken on the inside. But I should I also be considering something else?
