As you've learned, the i3 has no fog lights; the lights in the bumper of 2014-2017 i3's are halogen high beams. Some have replaced the halogen with LED bulbs, but the reflector is designed for the concentrated almost point light source of a halogen bulb whereas the light from an LED bulb originates from a larger area. This results in more scatter and poorer focus when LED bulbs are installed even though they are usually brighter and whiter.
You've also learned how to adjust them.
