To regain full visibility, that meant replacing the whole all-in-one headlight which was costly and frequent. In , the Federal Motor Vehicle Safety Standard was amended to allow composite headlight assemblies to include replacement bulbs, a nonstandard shape, and aerodynamic lenses. Since this amendment, headlights for the first time ever were manufactured from plastic. Since composite headlight units made it possible to replace the bulb instead of the whole unit, the replaceable halogen bulb became the preferred light source for headlights until the introduction of the HID headlight.
This helped produce adequate light levels immediately when starting up a vehicle and would reach their full brightness shortly after. Compared to halogen lights, HID headlights Xenon improved lamp life, lumens, high intensity beam patters, color temperature, and durability. Since the lighting units could be smaller without impacting the light emitted automotive designers were able to designs headlights more creatively. Europeans automotive manufacturers were again one step ahead as the first production car to host the HID light source was the BMW 7 Series in The LED headlight that we know today made its appearance in the Audi A8, primarily as a daytime running head light when the vehicle was in motion.
LED headlights reign supreme in efficiency since they produce substantially lower levels of heat than the previous generations of headlights. Since the diodes are relatively small, they can be manipulated into a range of different headlight shapes, the most unique at the time being the Audi R8 which used LEDs in every section of its headlight cluster.
Even though it sounds like something out of a James Bond film, laser headlights are the newest form of automotive lighting technology. Three diodes shoot blue laser beams into a prism, which focuses the three beams into one. The single beam is then passed through a phosphorous lens that transforms the blue light into a white light. Additionally, the passage of headlamp requirements into law reveals the degree to which automotive lights had already matured, for the benefits were now readily apparent beyond the industry and motorists at large.
By this stage, automobiles had without a doubt become an integral part of society. The whole point of these laws was to improve the safety of drivers, passengers and pedestrians.
The first federally implemented standards were introduced in by the IES. In an effort to better fulfill these requirements, engineers incorporated high and low beam options into headlights. The first cars to use this two-option lighting were rolled out in Simultaneously, European manufacturers were developing glare-reduction features for automotive headlights.
As the Roaring Twenties drew to a close, a growing number of cars were now being equipped with foot-operated dimming mechanisms. The technological innovations of the s revealed a growing awareness of the multifaceted demands that lighting entails.
From the outset of the Dustbowl Era, American automakers were scrambling to catch up with their European counterparts on technologies designed to reduce the glare from car headlights. Studies into the matter resulted in the adjustment of beam patterns, and hence the realization that light directed in a certain way could make things safer for drivers, and also less imposing on oncoming motorists. As the s progressed, the industry launched a slew of lighting innovations, including the replaceable glass lens, the integrated bulb and the metal reflector headlight.
As the Second World War demanded the attention of the world, car light innovations slowed, yet the auto industry witnessed one closely related development: a flashing light known as the turning signal. In , new cars began rolling out with hand-activated turning signals that would automatically switch off once a turn had been completed. As the decade advanced, turn signals became a standard feature in all American automobiles. This made it a lot easier to make left turns at four-way intersections, because a driver no longer had to manually signal fellow motorists.
Another innovation during the s was the integration of automotive lighting in vehicle design, which became more streamlined and practical. Not only did lights become easier to use, but they also grew more attractive within the design framework of automobiles.
From here on out, automakers produced smaller, rounder, more comfortable cars complete with optimal lighting — the likes of which are favored by motorists to this day. In terms of how lighting was viewed within the overall driving experience, various factors came into play during the s.
From this point forward, the objective extended far beyond simply making the best headlight bulbs for cars. As such, the s set the ball rolling on secondary lighting features in automobiles. The s saw further progress with the design and policies regarding sealed beam headlights. While American law required round sealed beams during the early years of the decade, automakers in Europe favored replaceable bulb headlights.
The big leap forward came in , with the introduction of sealed headlamps that contained a brighter filament for high and low beams. Within three years, lawmakers green-lighted the use of separate headlights for beams of both intensities.
With these latest innovations, it was now easier to drive at all hours, day and night. Under the clear midday sun, headlights would generally be off except when parking in garages and pulling into dark areas.
On rainy days, however, low-beam lights would keep each car alerted to others in close proximity on busy highways. In the early evening, low beams were also helpful during the transition between light and dark.
Later in the night, high-beam lights would make it easier for drivers to navigate dark roads. As such, drivers were greeted with far fewer paved roads or street lights, especially across the vast stretches and deep pockets of Middle America.
OK More information. This offered the opportunity to combine the knowledge in lighting technology of two companies with longstanding experience. Both companies founded together Automotive Lighting. Below you will find some key milestones in the evolution of lighting technology and some major events.

Halogen headlamps, like their tungsten precursors, are filament lights. This means that an electric current is run through a metal filament until it glows with incandescent light.
So if xenon headlights are the latest in a series of different car headlights, they must be a pretty new technology, right? Well, not exactly. In fact, they may be older than your parents or even grandparents, in some cases.
