In the dark, the facelifted 3 Series stands out with its lighting technology. The headlights now feature LED indicator “eyebrows†above them to give the car a more concentrated look. The taillights are new as well and feature a full LED treatment as standard. The changes are subtle but effective, as the light bars inside of them have been changed to give the classic BMW “L†shaped design a curvier look. The indicators are also LED, and they now stretch the length of the taillight. This allows the indicators to be better seen and therefore safer and better looking.
