To be honest with you I would go with the E46 style M3 mirrors, that's what I'm shooting for, I had the ones with the LEDs on my other car...
1. One of the LED on the blue side when out so instead of 3 LED lighting up I had 2, I still had the amber color that I could use tho.
2. Limited Vision.
3. Yes they are tinted blue they are hot looking, BUT the mirror is not "mirror" is more like plastic that will warp and distort vision.
IMO skip them both and if you like take a look at the E46 style that is what i'm getting.
