It was first codified in the 1949 Geneva Convention on Road Traffic and later specified in the 1968 United Nations Vienna Convention on Road Traffic.
The colour of light emitted by vehicle lights is largely standardised by longstanding convention. LED headlamps were introduced in the first decade of the 21st century. In 1993, the first LED tail lamps were installed on mass-production automobiles. HID headlamps were produced starting in 1991. Halogen headlamp light sources were developed in Europe in 1960. By 1945 headlamps and signal lamps were integrated into the body styling. Self-cancelling turn signals were developed in 1940. The sealed beam headlamp was introduced in 1936 and standardised as the only acceptable type in the US in 1940. Tail lamps and brake lamps were introduced around 1915, and by 1919 "dip" headlamps were available. She did not patent these inventions, however, and as a result she received no credit for-or profit from-either one. Silent film star Florence Lawrence is often credited with designing the first "auto signaling arm", a predecessor to the modern turn signal, along with the first mechanical brake signal. Dynamos for automobile headlamps were first fitted around 1908 and became commonplace in 1920s automobiles. It did not have all-electric lighting as a standard feature until several years after introduction. The Ford Model T used carbide lamps for headlamps and oil lamps for tail lamps.

Reducing the amount of electricity the car is consuming will increase the distance you can drive before the battery is discharged. If the battery light is on and you’re still driving the car, turn off as many electrical accessories as you can, such as the stereo, air conditioning or heater, and avoid using electrical controls such as power windows. If you turn off the engine, you won’t be able to restart it if the battery doesn’t have enough charge left to power the engine’s starter motor. The car will continue running as long as some juice is left in the battery, but if the charging system isn’t working or you have a bad alternator, your car’s engine will stop running once the battery is drained. If the car’s dashboard battery light comes on, you might be able to make it home or to a service facility for a repair.
Among other signs that the alternator or other parts of the charging system aren’t working are dim headlights or the clock losing time. The charging system warning light should show for a few seconds when you start the car, but if the battery light shows while you’re driving the vehicle, that light signals a problem. This article refers primarily to conventional vehicles with conventional 12-volt batteries more electrified vehicles and those higher-voltage electrical systems will vary. The car battery itself may be the cause if it has corroded cable terminals, bad wiring, damaged cells or plates inside or if it is leaking electrolyte. If the alternator fails, or the accessory belt that drives the alternator is loose or broken, then you’ll end up with a dead battery because the bad alternator isn’t recharging the battery. The alternator generates the power that is stored in the battery. The cause of the battery light could be a loose or corroded battery cable or other wire connecting components of the charging system, or it might be a problem with the alternator or voltage regulator. CARS.COM - If the battery warning light (a light in the shape of a battery symbol) on the dashboard comes on while you’re driving, that means the charging system isn’t working, but the fault may lie in something other than the battery.
