Tesla has a tradition of hiding whimsical software features to be discovered by owners in its Model S – and now Model X – and the latest is a multi-colored light display.

By pressing the charger button 10 times while plugged in, the LED light ring begins to go through a sequence of rainbow colors akin to the Rainbow Road Easter egg in its infotainment screen.

Other Easter eggs have included the info screen in a Model S transforming to an imaginary James Bond submarine, and the novelty of it all is one more thing that differentiates Tesla from other carmakers.

Following is the latest charger port rainbow.

Below is the interior rainbow road reminiscent of the Mario Kart game.
