when i drive at night i notice the dome light is always on is this normal??? is right by the sunroof buttons

 

Yes, it's normal for the one light to be on all the time and I don't think you can turn it off.

 

Yes, it's just an ambient lighting. Most newer Lexus vehicles have it as far as I'm aware. The nice thing is that it isn't really distractive any.

 

Is there a dome light or reading light? I test drove one at night but didn't find a light that you could read by. Is the ambience lighting (blue led's) all there is?

 

there are spot lights for front and back passengers, the same blue LED lighting. the buttons are located in the same area to the left and right - they are hard to distinguish from the other overhead buttons because the buttons are all side by side. unfortunately, they aren't terribly bright for reading.

 

Your spot lights are blue?? Mine is white, same as the one that's always on.
The RL lights blue when i test drove the acura, but I thought the lexus was white.
