I had a 2017 March 90D for a few days but had been driving a pre face lift P90D loaner for about a month. Other than the amazing acceleration and more solid AP1, I noticed that the old headlights seems to be a lot better, specially the low beam. They through a brighter, more even beam that cuts off nicely at the top. The new LED are dimmer and has an uneven pattern. I did some Googling and confirmed that the old lights are indeed better, and the new ones are in fact poorly rated by IIHS. So... is it possible to retro fit the old lights in a face lifted model S? Do any one know if Tesla will be updating the lights soon? If so, do you think a retrofit to the new ones will be possible?
