Locate The Fog Light Assembly

Knowing where the fog light assembly is helps you change the fog light easily. On the 2018 Jeep Compass, the fog light is near the front bumper.

Before changing the fog light, you need to find the assembly. This saves time and avoids damage.

Find The Front Bumper Area

The fog light assembly is behind the front bumper. Look near the lower part of the front bumper on each side.

The fog lights are small round lights set lower than the main headlights. They help with visibility in foggy weather.

Remove The Splash Shield

The splash shield protects the fog light area from dirt and water. It blocks access to the fog light housing, so you must remove it first.
