darthalomus Posted September 21, 2014 Report Share Posted September 21, 2014 I have one of these mirrors. it has the power button in the middle and what appears to be two lights on either side. (See image by following the link) http://preview.tinyurl.com/mtnx8y7 My question is in regards to what appears to be the two lights; one on either side of the power button. When I press the power button should both lights come on or just the one on the left? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
dhh3 Posted September 23, 2014 Report Share Posted September 23, 2014 (edited) I believe the power button turns the auto dimming function on and off. The left green light will be lit when the function is on. The other one is the sensor that reads the intensity of light coming to the mirror, which makes it turn dark. Turn it on, and shine a flash light on the sensor - you will see the mirror turn dark. Edited September 25, 2014 by dhh3 jkeaton 1 Quote Link to comment Share on other sites More sharing options...

dhh3 Posted September 25, 2014 Report Share Posted September 25, 2014 I never knew why these mirrors had a power button, but I did find out with my Nitro. The Nitro had a sunroof, and as soon as I opened it, the mirror would change to black, unless I turned it off. Quote Link to comment Share on other sites More sharing options...
