When cars were first being produced, the headlight was more of a lamp, with an enclosed acetylene flame that had to be manually lit by the driver. Those early headlights were introduced in the 1880s and gave drivers the freedom to be able to drive more safely at night. The first electric headlights were produced in Hartford Connecticut and were introduced in 1898, though they were optional on new car purchases. They had a short lifespan due to the incredible amount of energy required to produce a light bright enough to light the roadway. When Cadillac integrated a modern electrical system into automobiles in 1912, headlights became standard equipment on most vehicles. Today’s vehicles have headlights that are brighter, last longer, and have multiple facets; such as daytime running lights, the low beam, and the high beam. https://www.dtsanyparts.com/whee...-wheel-loader-lg855.html
