What are the lights on my side mirrors for?

The lights on your side mirrors serve an important purpose in ensuring your safety and the safety of other drivers on the road. These lights, known as side marker lights or side turn signal lights, provide crucial visual cues to other vehicles around you, helping to prevent accidents and improve overall driving conditions.


What Are Side Marker Lights?


Side marker lights are small, usually amber-colored lights located on the side of your vehicle, near the front and rear wheels. These lights are designed to make your vehicle more visible to other drivers, especially in low-light conditions or when changing lanes. They help other drivers identify the size and position of your vehicle, allowing them to better anticipate your movements and react accordingly.


Why Are Side Marker Lights Important?


Side marker lights serve several important functions:



  • Increased Visibility: The lights make your vehicle more visible to other drivers, especially in low-light conditions or when your headlights are not fully illuminating the sides of your car.

  • Lane Change Awareness: When you signal to change lanes, the side marker lights help other drivers on the road understand your intentions, allowing them to adjust their speed or position accordingly.

  • Accident Prevention: By making your vehicle more visible, side marker lights can help prevent accidents, especially in situations where a driver may not have a clear line of sight to the front or rear of your car.

  • Legal Compliance: In many countries and states, side marker lights are a legal requirement for all vehicles, ensuring a consistent standard of safety on the roads.


Overall, the lights on your side mirrors play a crucial role in keeping you and other drivers safe on the road. By understanding their purpose and importance, you can be a more responsible and attentive driver, contributing to a safer driving environment for everyone.
