The Sajjdah 1426 LED prayer rug lights up when it is properly oriented toward Mecca. As it is turned toward Mecca, the brighter it's lights glow.
The Sajjdah 1426 prayer rug contains batteries, LEDs and of course a compass to determine when the rug is properly oriented.
The Sajjidah 1426 was created in TURKEY by Turkish designer Soner Özenç.
(Embedded inside the Turkish tapestry is a compass that enables the rug to detect when it is being pointed toward Mecca. The closer it is to facing the sacred site and holy city in Saudi Arabia, the brighter the lights glow. )
