L-N-H knob

[kmammas]

I don't remember if the N L H knob on my LX470 had been lit up.  I see that now it is dark, but seem to remember that the N L H letters on the top of the knob were lighted.  Can't find any information on this online.  If someone could please let me know it would be appreciated.  I can't find anything online about changing the bulb or pictures of the knob lit at night.  I seem to remember that the knob lit up in green.  Can someone please check their LX and let me know if their N L H know lights up.  Thank you.
