The Tesla modelx does not have the switch cable to install the atmosphere light, because the atmosphere light of the original car is enough to meet the needs of the owner. Ambient lights are usually powered by the car's built-in circuitry, so there is no need to add a separate switch wire. If you want to add atmosphere lights to your Tesla modelx, please contact an authorized Tesla service center for professional modification to ensure that the modified atmosphere lights are compatible with the original car circuit, ensuring safety and stability.
