• Work Light: A strong work light will help illuminate the area you’re working on.

Locate the Headlight Assembly

The headlight assembly is located on the front of your Jeep Grand Cherokee, behind the grille. You’ll need to access it from the engine bay.

Open the Hood and Disconnect the Battery

1. Open the hood: Locate the hood release lever inside the vehicle and pull it to open the hood.
2. Disconnect the battery: For safety, always disconnect the battery before working on any electrical components. Locate the battery, usually in the engine bay, and use a wrench to loosen the negative terminal clamp first, then the positive terminal clamp.

Remove the Headlight Assembly

1. Remove the screws: Locate the screws holding the headlight assembly in place. These screws are typically located on the top and bottom of the assembly. Use your Phillips screwdriver to remove them.
2. Disconnect the electrical connector: Carefully disconnect the electrical connector that powers the headlight bulb. This connector is usually located on the back of the assembly.
3. Remove the assembly: Once the screws are removed and the electrical connector is disconnected, gently pull the headlight assembly forward to remove it from the vehicle.

Replace the Headlight Bulb

1. Access the bulb: Locate the old headlight bulb within the assembly. Depending on your model, the bulb may be held in place by a spring clip or a twist-and-lock mechanism.
2. Remove the old bulb: Carefully remove the old bulb by releasing the clip or twisting it counterclockwise.
3. Install the new bulb: Gently insert the new bulb into the socket, ensuring it is properly seated. If the bulb has a spring clip, ensure it clicks into place. If it’s a twist-and-lock mechanism, twist it clockwise until it’s secure.

Reassemble the Headlight Assembly

1. Reconnect the electrical connector: Carefully connect the electrical connector to the new bulb.
2. Secure the assembly: Replace the screws that hold the headlight assembly in place, ensuring they are tightened securely.

2. Reconnect the negative terminal: Reconnect the negative battery terminal clamp.

Test the Headlight

After reconnecting the battery, turn on your headlights and ensure the new bulb is working properly. If the new bulb doesn‘t light up, double-check the electrical connector and ensure the bulb is properly seated.

Final Steps and Maintenance Tips

• Dispose of the old bulb properly: Headlight bulbs contain hazardous materials, so dispose of them responsibly. Check with your local recycling center for proper disposal guidelines.
• Regular Inspection: Inspect your headlights regularly for signs of damage or wear. This will help prevent unexpected failures and ensure optimal visibility on the road.
• Clean the headlight lens: Clean the headlight lens with a soft cloth and a mild cleaning solution to remove dirt and grime. This will help improve light output and visibility.

Beyond the Basics: Understanding Headlight Types

Your 2018 Jeep Grand Cherokee might feature different types of headlights, including:

• Halogen: These bulbs are the most common and affordable option. They produce a yellowish light and have a shorter lifespan compared to other types.
• HID (High-Intensity Discharge): HID bulbs offer brighter, whiter light and last longer than halogen bulbs. They require a ballast to operate.
• LED (Light-Emitting Diode): LED headlights are the most energy-efficient and long-lasting option. They also produce a bright, white light.
