This feature in the Rolls-Royce Phantom blew us away

For more than a century, Rolls-Royce has been producing some of the most iconic and luxurious motor cars in the world. Over the past two years, I've had the opportunity to experience the Ghost, the Wraith, and the company's flagship Phantom firsthand.

And I've been duly impressed by all of three cars.

In my most recent encounter with Rolls-Royce, the ultraluxury brand dropped of a 2016 Phantom sedan at Business Insider's headquarters to check out for a few days.

Even though the Phantom was packed to the brim with luxury features ranging from book-matched wood veneer to power-closing coach doors, one feature stood out above them all: the Rolls-Royce starlight headliner.

I know it's hard to get excited about the ceiling of a car, but trust me. This is cool.

The headliner features a series of fiber-optic lights mounted inside the ceiling of the car. But the design of the lights make it look like constellations in the sky.

Here's a closer look at the Rolls-Royce starlight headliner:

As nice as the plush rear seats may be, the real show starts when you look up!

Here it is: the starlight headliner. The headliner is one of Rolls-Royce's infinitely customizable bespoke features.

The headliner is also available on the Wraith coupe and the Ghost sedan.

Each headliner is assembled by hand and tailored to the owner's wishes. Rolls-Royce can mimic just about any constellation.

Not only is the headliner aesthetically pleasing, it's also an effective way to light the interior of the car. Here you can see it light up the interior of a Wraith.

That's because the brightness of the starlight headliner can be controlled using the car's infotainment system.

Each headliner can feature anywhere between 800 and 1,600 fiber-optic lights. Our Phantom came equipped with about 800 lights.

According to Rolls-Royce, the headliner takes two craftspeople an average of nine hours to create by hand, although more complex designs can take up to 17 hours.
