What are the lights on side of headlights?

The lights on the side of headlights, often referred to as side marker lights, are an important safety feature on vehicles. These lights serve a specific purpose and are designed to enhance visibility and improve road safety.


What are Side Marker Lights?


Side marker lights are small, additional lights installed on the sides of a vehicle's front and rear fenders or bumpers. They are typically amber or red in color, depending on their location on the vehicle. These lights are required by law in many countries to help make vehicles more visible, especially during low-light conditions or when the vehicle is turning or changing lanes.


Purpose of Side Marker Lights


The primary purpose of side marker lights is to increase the visibility of a vehicle from the side, making it easier for other drivers to see the vehicle and its position on the road. This is particularly important in the following situations:



  • Low-Light Conditions: Side marker lights help make a vehicle more visible in the dark, dusk, or other low-light conditions, reducing the risk of collisions.

  • Lane Changes: When a driver is changing lanes, the side marker lights help indicate the vehicle's position and intended direction, allowing other drivers to anticipate the movement and react accordingly.

  • Turning: Side marker lights also help signal a vehicle's turning intentions, improving safety and reducing the risk of collisions during turns.

  • Parked Vehicles: For vehicles parked on the side of the road, side marker lights help make them more visible to other drivers, reducing the risk of collisions.


By enhancing the visibility of a vehicle from the side, side marker lights play a crucial role in improving road safety and reducing the likelihood of accidents.


Legal Requirements for Side Marker Lights


The legal requirements for side marker lights vary by country and jurisdiction. In many countries, including the United States and European Union, side marker lights are mandatory for all vehicles, with specific regulations regarding their placement, color, and brightness. Failure to have properly functioning side marker lights can result in fines or other penalties for vehicle owners.


Ensuring that your vehicle's side marker lights are in good working condition is an important part of maintaining road safety and complying with local laws and regulations.
