1999 KA 1.3 Ghia Electrical / bulb / lighting issues?

My KA (T Reg) runs well but over the last couple of months, the dash/instrumentation lights worked intermitantly and now not at all. Worse than that, the side lights both front and rear have stopped working too. Indicators/main lights/brake lights etc..all fine. Have checked the fuses and no worries there. Could it be relays? Any thoughts gratefully received as I am far from an electrician!! Thanks
