When you turn the cab lights on (377) should it just be the far right light in the ceiling that activates? When in a tunnel or at night the cab is incredibly dark - can't see any buttons or switches.....? it looks like there are 4 ceiling lights but as mentioned only far right one activates. I know there is a mini side light but that offers little illumination either.
If you look by the bottom of the cab door there is a button to the side of it that turns on all of the lights.
