1966 Canadian built valiant custom 200 convertible

I am new to this. My husband will help but I want to learn and do as much of it as I can on my own. Currently pulling my instrument cluster to see if replacing bulbs is needed or some fixing of wires (no panel lights working except blinkers and oil light) I need that for my safety. Other than needing a new headliner the interior is all good. Thankful for finding this page - it’s been very informative already!
Could be your headlight switch. The instrument lights go though it for power. When rotating the knob clockwise or counter, do they come on at all?
