What does DIADEM mean?
The DIADEM is an innovative lamp with interference coating, which produces yellow light. Due to the interference coating the DIADEM produces an amber colour when lit and features an opalescent white surface – without the “mirror effect” of normal yellow coloured lights. The DIADEM supports the cool and stylish look which car designers desire to produce with all clear and transparent headlamp modules. The DIADEM is interchangeable with other yellow signal lamps (in front and in the back of the car) and it is approved for use throughout Europe. Besides, the DIADEM offers twice the lifetime of the standard yellow signal lamps.
