For some standard inst' panels the only lamp that come on with switch on is OIL warning. Others light up a SEATBELT warning. The rally panel has none unless the park brake is set. Only sign of life in these is fuel gauge needle movement. So without knowing what panel you have,,, I'll guess a couple of bulbs burned out, or bulb sockets failed, or both. The sockets have 2 tiny plastic tangs that hold them in position. If you pull the inst' panel and find one or two bulb/socket failures, best plan is replace all of them while you're there.
