The future of automotive headlights is very bright indeed, pun intended. Nonetheless, the path there hasn\u2019t always been as well lit as it is now. With recent technological advances in lighting, we can see more and more cars equipped with better headlights that make for a safer driving experience.<\/span><\/p>\n

As things progress, there\u2019s been a huge leap forward that will see \u201csmart\u201d headlights that aren\u2019t just brighter but are capable of actively picking out or not illuminating certain subjects on the road. Here’s all you need to know about car headlight technologies available on the market today.<\/span><\/p>\n

A Brief History of Headlights<\/b><\/h2>\n

Generally, modern headlight technologies can be split into four types. That\u2019s halogen, high-intensity discharge (HID) \/ xenon, light emitting diode (LED) and laser.<\/span><\/p>\n

The very first headlights were acetylene gas headlamps and not grouped with the aforementioned four above. You might recall them from old movies in the early 1900s that saw the driver open the glass cover and lighting the element on fire. Yes, it was literally the incandescent light of a flame being vaguely reflected to attempt illuminating the road ahead.<\/span><\/p>\n

Electricity is a wonderful discovery though, and it has led to the introduction of the first halogen headlights by Italian carmakers in 1962. Although still very much an incandescent light, the bulb housed a small trace of bromide or iodine halogen that resulted in a brighter, yellowish glow.<\/span><\/p>\n

From there, the next step in automotive lighting was HID lights. Commonly referred to as xenon, it provided a brighter light and was more durable, lasting at least twice as long as a halogen system.<\/span><\/p>\n

Soon came LED lights. Audi were the first to implement them in its Audi A8 as DRLs but Lexus is universally accepted as the first to actually implement LED lighting for the low beams in the headlights of their Lexus LS600h back in 2007.<\/span><\/p>\n

The latest innovation in car headlight technology though, might sound like something out of science fiction; lasers. Yes, lasers. But fret not, you won\u2019t go blind if you accidentally look into them, as we\u2019ll explain why below. Lasers are naturally the next step in automotive lighting as they offer a near parallel beam of light 1,000 times more intense than LEDs but with less than half the energy requirements.<\/span><\/p>\n
