When Was the Turn Signal Invented?
The Need for Turn Indicators
Driving down the road without proper signaling can be dangerous for both the driver and the other vehicles on the road. It’s crucial for drivers to be able to signal their intentions, especially when they are turning. Turn indicators have come a long way from the days of hand signaling, and today it is a crucial safety feature on any motor vehicle.
Before turn signals were invented, drivers had to signal their intention to turn using hand signals. This meant extending your hand and pointing it in the direction you intended to turn. While effective, hand signaling required drivers to take one hand off the wheel, which could be dangerous, especially when driving at high speeds. Hand signals could also be difficult for other drivers to see if the lighting conditions were poor or if the driver’s arm was obscured.
Early Turn Signal Inventions
The first electrical turn signals were invented in the early 1900s. The first patented design was developed by Percy Douglas-Hamilton in 1907. His invention featured an illuminated arm that extended from the side of the car to indicate a turn. However, this early design was not widely adopted, and it would be several years before turn signals became commonplace.
Other inventors tried their hand at creating turn signals throughout the early 1900s, but most designs were complex and expensive to manufacture. It wasn’t until the 1930s that turn signals became standard on most vehicles.
The first automatic turn signals were introduced by Buick in 1938. These signals were controlled by a switch on the steering column and used a series of lights to indicate a turn. This design was quickly adopted by other automakers and paved the way for the turn signals we know today.
Standardization of Turn Signals
By the 1950s, turn signals had become a standard feature on all new cars. However, there was still no standardization between automakers, meaning that turn signals on different cars could operate in different ways. This lack of standardization was confusing for drivers and made it more difficult for other drivers to predict a car’s actions.
In 1963, the US government passed legislation requiring that all cars sold in the United States be equipped with turn signals. This marked the beginning of standardization for turn signals. In Europe, turn signals were required on all vehicles by 1968.
Today, turn signals are a legal requirement on all vehicles in many parts of the world. They are essential for safe driving, helping to reduce accidents and make the roads safer for everyone.

How Do Turn Signals Work?
Turn signals are a vital component of any vehicle on the road. They allow drivers to communicate their intentions to other drivers, making the roads safer for everyone. But how do turn signals work? In this section, we’ll explore the inner workings of turn signals and how they function.
Wiring and Electrical Components
Turn signals work by utilizing a combination of electrical components and wiring. The turn signal switch, located on the steering column, sends an electrical signal to the turn signal relay, which activates the turn signal lights. The lights themselves are typically made up of an incandescent bulb or an LED (Light Emitting Diode).
The wiring of turn signals is relatively simple. When the turn signal switch is engaged, it completes an electrical circuit that activates the turn signal lights. The relay is responsible for ensuring the lights flash at the correct rate, and in most modern cars, this is achieved with a small computerized module.
Activation and Timing
Activating turn signals is typically achieved by using a lever or button located on either side of the steering wheel. When the driver pushes the lever or button in the direction they wish to turn, the turn signal switch engages and sends an electrical signal to the relay. The relay then activates the turn signal lights, which flash in a sequence to indicate the direction the driver intends to turn.
The timing of turn signals is critical to their effectiveness. The flashing lights must be visible to other drivers and pedestrians without causing confusion or distraction. For this reason, turn signals usually flash between 60 and 120 times per minute, depending on the country and vehicle manufacturer. This rate is regulated by laws in most countries to ensure consistency and effectiveness.
LED vs. Incandescent Turn Signals
LED turn signals have become increasingly popular in recent years, and for good reason. LED lights are much brighter than incandescent bulbs, making them easier to see, especially in bright sunlight or inclement weather. They also consume less energy, which can result in improved fuel economy and decreased carbon emissions.
Incandescent bulbs, while not as bright as LEDs, are still a popular choice in many vehicles. They are typically less expensive to manufacture, making them a common choice for automakers. Some drivers also prefer the warm, yellowish glow of incandescent bulbs over the cooler, bluish light emitted by LEDs.
In conclusion, turn signals are an essential safety feature of any vehicle on the road. They work by utilizing a combination of wiring, electrical components, and flashing lights to indicate the driver’s intentions to other drivers and pedestrians. Whether you choose LED or incandescent turn signals, it’s crucial to ensure they are functioning correctly and that you use them every time you turn or change lanes.
