What Are Parking Lights?
Parking lights, also known as sidelights, are essential low-intensity lights mounted on both the front and rear ends of a vehicle. These lights automatically illuminate when the vehicle is parked in low-light conditions, enhancing visibility for other road users.

The Functionality of Parking Lights
The primary role of parking lights is to indicate the position and perimeter of a parked vehicle during the night or in adverse weather conditions such as rain or fog. Their placement on the corners and sides of the vehicle’s bumpers allows them to outline the vehicle’s location, significantly reducing the chances of accidents or collisions with other oncoming vehicles, cyclists, and pedestrians.
When to Use Parking Lights vs. Headlights
Parking lights should be utilized in specific situations such as parking overnight on poorly lit streets, or when your vehicle is stationary on the roadside while waiting for assistance. Although they provide significant visibility, they are not designed for driving. Using only parking lights while navigating can create potential risks by impairing visibility on the road, and may lead to legal issues in some states where the use of headlights is mandated under low-light conditions.
In summary, while parking lights serve an important purpose in ensuring that a stationary vehicle is visible to others, they should never replace headlights when driving. Understanding their usage can help maintain safety on the road.
