Just got a 2012 Nissan Frontier. It has lights on the rearview, green one on left always on, and the other one stays off. I don't have the Homelink system and can't find anywhere in the manual what else they might be for. Anyone know?
You may have the auto dimming rear view mirror. Nissan calls it (automatic anti-glare) Owners Hand Book section 3 page 15 Green light on means that when head lights from cars behind hits the sensor photooptic cell that causes the liquid crystals inside the mirror glass to darken. Good Luck
