Abstract—The vehicular illumination system has undergone considerable technological advances in recent decades such as the use of a Light Emitting Diode (LED), HID (high intensity discharge) and laser application now. The challenges around global products have been lately one of the key challenges for the Lighting community. This paper will present a survey which was held with costumers from China, India and Brazil understanding the difference and similarities regarding the lighting attributes. It brings also a discussion how to develop a lamp globally that fulfils everyone's needs and addresses potential trade-offs in design and performance.
