Side marker lights with the uber ugly USDM orange reflector (non US cars dont have either the amber reflector or the amber LED on the circuit board directly behind it).
Note that these are NOT in the location of either the fogs (outer edge) or the DRL LED strips (running from the reflector, out toward the fog lights).
The side marker lights are in the same location and behind the same amber reflector on all Model 3s fitted with them.
Some of us have either a. replaced the amber with a clear reflector b. painted over the reflector c. removed the reflector (exposing the dark PCB and both LED chips behind it).
Search this and the other forum if interested.
