If you have a 760 V6 GLE of about 87/88 and you have an external air temperature gauge [bottom left hand corner of the dashboard under the fuel gauge] with lcd type display......... does it light up with the panel lights, I thought mine did once but perhaps not? I know you get a nice red led at 2degC and below but being able to read it at night would be nice. Not show in my Haynes manual needless to say.
