Tesla CEO Elon Musk revealed on Twitter that owners of the company's SUV, can enjoy their own holiday light show.
The "Easter Egg," hidden in the latest software update of the Model X, plays the tune of Tran-Siberian Orchestra's "Wizards in Winter" to a synchronized sequence of headlight, fog light and turn signal flashes. The SUV's signature falcon wing doors also open and close in time to the music.
The three minute display is the latest in a series of hidden hacks built into the operating system of Tesla's electric vehicles. The over-the-air update is rolling out to customers just in time for the Christmas holiday.
