21st century witnessed tremendous progress in the application of Photonics, one of the prominent being lighting industry. The automotive lighting, among various categories of lighting, received immense growth. The lamps which have once been mere candles or lanterns now comprise of several components strategically packed into various sizes, shapes tailored to add unique aesthetics to the vehicle. The current day lamps are not only complex in the structural aspect but also in the end functionality making (night) driving experience dynamic, smart, and safe. For several years such intelligent systems were mere R\&D, marketing ideas but the recent changes in legal regulations, (including the recent approval for AFS in the US) made ‘AFS’, ‘ADB’, ‘Grill lighting’ etc. conventional on the latest vehicles around the world. These rapid transitions, together with the continuous advancements in electronics sector, manufacturing technologies, and automotive qualified materials make the new generation lighting system designs more challenging, competent. In this article, we attempt to provide an overview of some of the current day challenges the lighting designers are encountered with. We present the challenges associated with the development of ‘Efficient High Power Lighting System’. The state of the art market demands of such systems, some of the key limitations of the current design solutions are outlined in this article.

Automotive lighting is another vast and important application of photonics. In automotive exterior lighting, there are two main division - i) To see and ii) To be seen. Headlamps are ‘to see’ functions and their performance is of prime importance. A well illuminated drive-way can give the driver a smooth driving experience without straining eyes in night-time. That, in turn, ensures safety for the driver and other road users as well. Such requirements have brought tremendous changes in this field and it developed beyond imagination in the last couple of decades. Here we discuss the history, the cutting-edge technologies and the challenges came up with it. In the end, we provide an overview of one of the novel headlamp technology , compact lightguide headlamp.
