ok after driving at night it worked great. one thing to note is the auto dim function in city driving. you will have headlights coming at you alot and center highway lights shining on your windshield. this cuased the mirror to be less dim then normal if a car is behind you. my solution will be one of two things. i could open up the mirror splice in a interupt switch to the front photocell to cut its light sensing off. or somehow rig a small hatch or something to cover the sensor. Its definetly not a big deal. i just wonder if i could rig this up.
