Offer LEDs for all headlight functions.
LED headlights allow to dim light that would shine directly onto oncoming vehicles but continues to cast its full light on the zones between and beside them. This works because the LED high beams can be split into many individual light-emitting diodes.
LEDs are considerably more complex to design and costly. Early cars that used LEDs often had far dimmer light than HID designs, but the latest designs are comparable.
First implemented on the Model X and with the Model S refresh in April 2016, and now every new Tesla uses an all-LED design.
