Thermometer for outside temp uotside the car,must have illuminated scale

I am looking for a dash mount thermometer for Oldsmobil alero 1999 2.4 l
I know the japanies car are equipped with such.
But the american are kind of behind when it comes to small extra goodies.
In Norway with changing driving condition with snow an ice it is very handy to know the outside temp.

Looking forward to get some information.
The readout meter must be illuminated using 12 volt
