I have made this mistake several times. It is a frustration I have with newer cars. Only cars I own are older, where the gauge cluster uses only ambient lighting when the headlights are turned off. When nightfall hits, the gauge cluster is totally dark. So to see the gauges, I have to turn on the lights. Newer cars, the gauge cluster is always lit. there’s just a dimming effect when lights are turned on, and possibly a minuscule indicator that the lights are on. This is a feature that is worse on new car models than old!
