As part of a project involving a new concept Smart vehicle, chemical company giant BASF teamed up with Philips to create an interesting vehicle interior lighting concept using a transparent roof.

As tomsguide.com reports, they may just look like hexagonal pieces of glass, but this car's roof is filled with OLED lights and solar cells. In the day time the OLED sun roof is transparent, letting you see outside the vehicle while collecting solar energy to power its interior lighting system at night.

At night or when the OLEDs are switched on, the roof becomes a honeycomb of glowing OLEDs that provide light which can only be seen from the interior of the vehicle, minimizing distractions to other drivers.

Although the technology is still only in its prototype stages, something more can definitely be expected from this partnership in the future.
