I waited until nightfall to check for sure which lights on my 90 Westy dash
actually light up.  And they are...

Speedo gauge,
Tacho gauge,
Digital clock,
Idiot lights panel for turn signals, battery, oil, and high beam,
Demister rocker switch,
Hazard lights rocker switch,
Rear heater fan,
Ventilation slide controls,
Front heater fan,
Cigarette lighter.

My headlight switch does not light up at all and nor do my two air con
rotary switches and nor does the dimmer switch.  And the dimmer switch dims
everything except my radio panel (original Heidelberg).  I can't remember
for sure but I don't think the red pilot light on the emergency hazard
rocker switch dims.

Cheers
