What Differentiates a Side Marker Light from a Corner Light?

Given that your car has a variety of automotive lighting options, it’s not unusual for you to mistake two supplemental lights for one another, especially if they share a similar appearance or are located next to the same part.

On the sides of your car, you’ll find corner lights and side marker lights, but they serve different purposes. Simply put, the former gives additional lighting in low visibility situations, while the latter aids in other drivers being able to see your vehicle—your position, where you’re turning, and similar—from a distance.

With the help of side marker lights, you can provide other drivers with a clear picture of your vehicle’s location and direction of movement from a variety of angles. They are typically situated close to your car’s bumper, fender, or rear quarter panel and blink or illuminate with the headlights of your car or with the directionals.

As was already said, corner lights aid in increasing visibility when turning. They perform similarly to headlights in that they cast a light beam over a specific section of the road.

They are not regarded as indicator lights because they are not used to indicate a turn or communicate with other drivers.
