Are high beam lights the same as brights?

High beams are sometimes referred to as 'brights' or 'full beams'. The light beam for high beams is angled upwards in order to illuminate a surface area above and beyond the light of the low beams. High beams have a long-range focus. Unlike low beams, high beams will never turn on automatically.

Why do my low beams work but not my high beams?

In the 1940s, headlights began to look a little more like the headlights of today. 1940 saw the first round sealed beam headlight. For decades afterwards, American cars were only permitted to use round sealed beam headlights, making them the industry standard. These sealed beam headlights meant that drivers couldn't replace their headlight bulbs.

When did electric headlights start?

As automobiles grew in popularity, headlights improved. In 1912, Cadillac created cars with the first modern electric system, including electric headlights. In 1913, Henry Ford began mass-producing the Model T, and the automobile industry took off.

When were halogen bulbs introduced?

Halogen builbs, which have become standard on today's cars, were introduced in Europe in the 1960s. Again, the United States lagged behind, due to outdated regulations. American cars were legally limited to much dimmer headlights and couldn't take advantage of the new halogen bulbs. The US caught up with Europe in the 1980s, and headlights are now virtually the same on either side of the Atlantic.

When did the automotive industry start using sealed beam headlights?

The mid-1910s also witnessed the rollout of electric headlamps among European automakers.

What is a halo headlamp?

Halo headlights consist of illuminated rings that light whenever a vehicle is in operation, day or night. Though initially an exclusive hallmark of BMW, the halo headlight has been adopted by other automakers in the years since its debut.#N#In effect, halo headlights function as shining rings for vehicles. As with HIDs and LEDs, halo headlights can be purchased as aftermarket replacement lights for existing vehicles.#N#The 2010s have seen further innovations on the lighting front, most specifically with the emergence of the laser light. The laser light works by generating concentrated light and turning it white with a lens. While the laser light has thus far been confined to luxury Audi and BMW models, the light is expected to grow in popularity in the coming years as more drivers learn of its power, durability and compact nature.#N#At present, the automotive market enjoys an almost overwhelming variety of headlight types. How this will ultimately play out in the history of projector headlights remains to be seen. Hopefully, automakers will relearn to balance aesthetics with quality, and not risk the latter just to boost the former for marketing purposes.#N#In any case, today’s drivers have their choice of the brightest headlight bulbs ever produced in the history of cars.

What was the first light source for automobiles?

As with the horse and carriage, the early automobile was limited in terms of its lighting source. The earliest cars were at first lit with kerosene oil. Soon thereafter, acetylene gas headlamps became the auto industry standard. The latter was particularly problematic for vehicles, because the light was only visible from short distances, and the gas could freeze during cold months. Consequently, it was difficult to navigate roads after dark.#N#Due in part to these limitations, early automobiles lacked interior lights and tail lights.#N#However, automotive and lighting engineers worked vigorously to develop a more satisfying system for the motor vehicle during the first few years of the 20th century. The effort initially paid off in 1908, which saw the introduction of the first carbon-based headlamp bulb to run on battery. Initially, however, the new headlamp was only available as a high-priced upgrade option to preexisting car owners.#N#Nonetheless, it must be stated that the history of automotive headlights truly begins during this period, because from the early 1900s onward, the race was on to make a light as conducive to, and satisfying for, motor vehicles as the light bulb had already proven to be for homeowners.#N#The world might have been decades away from the types of headlights that people know today, but the forward-thinking of engineers during this timeframe shows the extent to which manufacturers had a lasting vision for the automobile.

Why is it important to look at the history of automotive lighting?

Charting the rise and fall — as some people might call it — of automotive lights can help to provide a clear picture of whether a golden age has truly passed.

When did headlights become common?

During the early 1970s, all U.S. cars featured circular sealed beam headlights that were either dual or separate. At the request of U.S. automakers, who sought more designing liberties, federal highway laws were amended in 1974 to make way for rectangular headlamps. Within two years, the rectangular sealed beam headlamp was a common feature on newer makes and models by American car companies.#N#But while this did affect the appearance of the new cars, it didn’t affect the impact of the lights.#N#In the late 1970s, after years of resistance by American automakers, halogen bulbs began flooding into the U.S. By now, Americans had heard of the brightness and efficiency of halogen lights, which produced a fuller light than tungsten incandescent headlamps, yet used no extra power. Automakers soon caught onto how easy it was to manufacture automobiles with this low-cost lighting option.#N#Halogen lights swiftly became an industry standard — a phenomenon that has only recently been called into question.#N#In retrospect, the history of automotive headlights could be seen to have entered the last stage of its golden age around 1978, when halogen lights gained serious traction in the U.S. market. Halogen lights would dominate the auto industry for the next three decades, and remain the most familiar of the different types of headlights to most drivers.#N#Even though halogen lights have since been bested by newer headlight bulb types, the halogen light was the last to emerge in an era that favored quality over superficial aesthetic appeal.

When did the headlamp bulb come out?

The effort initially paid off in 1908 , which saw the introduction of the first carbon-based headlamp bulb to run on battery.
