There is no back lighting when your headlights are off. Mine burnt out in two parts, when my lights were on I could only read half of the panel, then they all burnt and I couldn't read any of it. I'm not positive but I think the numbers are always there, at night the back lighting comes on so you can read them. Go out with a flashlight and shine it on the panel at night, you should then be able to see them.

I'm 99% sure there is no back lighting when your lights are off. There might appear to be, but I don't believe there is. I also do not have a limited so I could also be very wrong. But all threads(and there are a lot of them) about IP lights and clock/climate control lights not working is always bad bulbs. Maybe someone with a limited can chime in here??

I'm going with Presta on this one. I seriously doubt your panel is back lite when the headlights are off.
If it is, it shouldn't matter if the car is running or not. Either way its not a common problem so there's no easy fix.
Maybe a couple pictures would help convince us non believers

Like I said, I could be wrong, I am just speaking from the experience I had with mine. I could read mine fine when the headlights were off, or during the day, but at night, with headlights on, it wouldn't illuminate and I couldn't read it. Are you assuming that because the display and numbers come on with the key, that that means its back lit? Not being an ass, just curious. I just went and looked at mine. Yes I could read it with the key on, but I don't believe that means its back lit. My advice to the OP is to follow the write ups and replace the bulbs, it will cost about $20 and 30min of his time. If that's not it, he has a problem I haven't read about before.

Yes, definitely back lit. I started it up in the garage (total darkness) and the backlight is obvious. You can't notice it in daylight.
Once you turn on the lights, the backlight dims and it's the instrument light brightness knob that controls the backlight. Just maybe the OP has the dash lights turned all the way down?

Keep in mind that its very possible the wiring is different from the early to late 4th gens.
I know Toyota changed the wiring slightly and then came out with this TSB (http://www.toyota-4runner.org/tsb/109012-tsb-el010-03-gauge-visibility-improvement.html) for the earlier models. Maybe that included other backlighting because when I get in my 4runner at night (no garage required) as long as I don't phyiscally turn the lights on I can start my truck and everything will remain dark.

Climate control panel doesn't light up at night
Hi everyone,
I know this thread is old, but I'm having the exact same problem as the original person that posted this. My mpg screen lights up fine as long as my headlights are off, but at night, when I turn the headlights on, the backlight on it turns off completely. Has anyone (or the original poster if by any chance he is still here) solved this?
Thanks!

This problem is real
I have the exact same problem as OP. I will attach images of the headlights off with both lcd screens backlit, and headlights on with only the radio backlit. LCDs are backlit during the day and off at night and the button lights won’t illuminate where the text is. I just replaced all the bulbs and this is how it works. Before replacing the bulbs the climate control lcd would never have backlighting. The first image is headlights off, the second is headlights on. Please send help for this very real issue
UPDATE SOLVED: I found that the dimmer switch for the days lights was disconnected. I reconnected it and everything works! I imagine if this is happening to anyone that the dimmer switch could be broken/disconnected. Hope this helps

LCD light causing drain?
Is the LCD display on a 2007 4Runner supposed to stay on once I turn the car off and shut the door? My battery died a couple days ago, granted it was 3 years old, but now I’ve started to notice that the display that shows the time and gas mileage stays orange when I turn the car off. When I peek in the window it only shows the time but I want to know if that could be drawing power still and causing damage to my battery?
