I've not not driven it much at night, but on Friday I was.
Basically, does it work. YES. It works.
Does it work all the time, or rather when I need it to work. NO
I've noticed that a car with "standard" non dazzling headlights will cause it to darken.
But, I've noticed that if a vehicle has these more modern "turn the road into daylight" headlights, the damn thing wont operate!
I have a theory, I may be well off the mark, but it goes like this.
The mirror shouldn't darken in actual daylight.
So, if the car behind headlights have a beam which is in the daylight spectrum, it fools the sensor and so wont darken.
Does this sound possible?
Many thanks for any ideas and help!

Yes you're right it's because the wavelength of the light is different and the sensor isn't able to cope with it
