Question: Tesla's taillight design has advantages?

No, there are no specific advantages to Tesla's Model 3 taillight design. The Tesla Model 3 taillights feature a large area of LED strip lights serving as the turn signal, brake lights, and reverse lights.

TIP: Solution for Tesla Taillight Fogging
The main reason for taillight fogging is usually high humidity in the air, causing water vapor to condense inside the taillight. In such cases, taillight fogging is a normal phenomenon, and it's solely related to the humidity in the air, not due to factors like washing the car, rain, or snow. Generally, the condensation of water vapor inside the taillight is not significant. After leaving the taillight on for 15 minutes, the moisture will evaporate, and it won't remain inside the taillight.
