headlight switch

My headlight switch rear fog lamp indicator and centre switch lights up, but the P, Sidelights, Auto, Main headlight indicators do not light up.....is this normal, or should they all light up, or should they light when centre switch lines up with them?...any help appreciated.

I have been putting up with the flashers/indicators occassionally stopping working. The hazards still worked. I have known for some time the problem was assocaited with the Illumination module in other words the headlight switch control unit as if I tapped it they would often start working...
