I just bought a 2007 TL and have a quick question. Can anyone tell me if the side mirror controls are back lit?

It seems that all the other controls are back lit for easy operation during night driving except for these (at least on my car).

Is this normal or do I have a problem?

 

Only the defog button is illuminated

 

Thanks!

 

i was freaking out about this too, i thought all of them burned out at once ... but yea they are not suppose to be lit
