As I mentioned above, sometimes my center console lights are on and sometimes the lights are off at night. It makes for finding the buttons a bit hard. I have a 2004 LS430. When the lights are working, the dimmer knob on the left side of the steering wheel does dim all those lights. I am talking about the lights around the console screen, the radio, and the a/c. Here are my observations. There is a light sensor somewhere that changes whether the screen is in day or night mode. Day mode has black lettering on a white background for the screen. Night mode has white lettering on a black background. I have noticed a connection with the lights not working and the screen going into Day mode when it is clearly nighttime. Any ideas?
