Brighter Dash / Gauge lights..?

I still have a problem with the dimmer though, but probably just worn some and not good contact. Is it normal to turn that dimmer switch all the way to the left, where it "clicks" and the dash lights stay on..? I can't remember if that's normal...lol
Pretty sure turning the knob all the way left past the click turns on the dome light. Turning it to the right decreases backlighting brightness
