Light on rear view mirror

Is that what they call the map light???? Anyone know how to make it light up? Is it battery operated? I thought I read that somewhere, but I have read so much info since I bought my set I can't remember? Can anyone tell me though how to make it light up?
thanks!!!

I had this option on my '75 roadster. If it is factory, and probably is there is an on- off switch right by the lens and no it is not battery operated. The wire comes in at the top of your windshield. I hope ths helps.

My 76 has this option as well. If you look at the bottom of the rearview mirror, there should be what looks like a little clear plastic lense with a little "stem" hanging down. Slide this (right is "on" I believe) and it should light up.

If it's hooked up, you should see a wire coming from the top where the mirror attaches to the windshield.

They are right I have one too it has a wire cooming off the main harness under the drivers piller pad going to the mirror. Mine works great !

When I first got my car the map light didn't work.After sitting for a while I think some corrosion must have set in.After operating the switch a few times it started working.I also had similar troubles with the washer/wiper switch.
