What is the trigger for the at temp, timing belt, turbo lights, charging and coolant light?

I believe my ignition switch may be in the way out from searching but wanted to check.

Occasionally when going key on, the lights aren't there until I hit the key to start.

Sometimes if I cycle the key they'll come on.

Today they aren't coming on regardless of key cycles until I start it. Trucks starting fine and everything else is powering up with the key in it's various positions.

Video for clarification

When they work


When they don't
