The blinkers assembly typically includes the housing, which is the outer casing that holds the bulb in place. This housing is often made from durable, weather-resistant materials like plastic or metal, ensuring the longevity of the assembly. Inside the housing, the bulb is securely mounted, usually through a socket that connects it to the vehicle’s electrical system. The bulb itself is a crucial part of the assembly, and its performance can impact the overall effectiveness of the turn signal system.

The bulb used in blinkers assemblies can be either incandescent or LED. Incandescent bulbs have been the traditional choice for many years but have now been largely replaced by LED bulbs in modern vehicles. LED bulbs are more energy-efficient, have a longer lifespan, and provide brighter, quicker illumination, making them a popular choice for blinkers. The type of bulb chosen also affects the brightness and visibility of the blinkers, which is critical for ensuring the vehicle is seen by other drivers.
