Direction indicator bulbs, also known as turn signal bulbs or blinker bulbs, are a type of automotive lighting component that are used to indicate the direction in which a vehicle is turning. These bulbs are typically located at the front and rear of a vehicle, and are activated when the driver uses the turn signal lever or switch. Direction indicator bulbs come in a variety of shapes and sizes, depending on the make and model of the vehicle. They are typically small, round bulbs that are mounted in a socket that is connected to the vehicle's electrical system. When the turn signal lever or switch is activated, an electrical current is sent to the bulb, causing it to light up and blink at a regular interval. One of the key advantages of direction indicator bulbs is their simplicity and reliability. Unlike other types of automotive lighting components, such as HID or LED headlights, direction indicator bulbs are relatively inexpensive and easy to replace. They also have a long lifespan, and can typically last for several years before needing to be replaced. Despite their simplicity, however, direction indicator bulbs are an important safety feature on any vehicle. By providing a clear and visible indication of a driver's intention to turn or change lanes, these bulbs help to reduce the risk of accidents and improve overall road safety.
