Stock xenon headlights look nice and look a million times better than the e92
headlights BUT the LED is worth it..
I was hesitant at first spending that extra 1900.
When I received my M4 a week ago and saw them in person, LED Headlights look amazing. So crisp, so futuristic looking, the color is unbelievable and just adds so much to the overall appearance to the front of the car. LED allows you to use the halo's as a headlight because they are more bright over the xenon projected halo's. it is an option to think about for sure.
