⚠️ Safety & Precautions

• Turn the lights off and let the bulbs cool before touching anything.
• If your truck has HID bulbs, the lighting system uses high voltage. Do not touch the bulb leads or ballast connectors with the system powered.
• Disconnect the negative battery cable if you are uncomfortable working around the headlamp connectors.
• Do not touch the bulb glass. Oils from your fingers can shorten bulb life.
• Support the headlamp housing carefully so you do not scratch the bumper or grille.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the hood

• Pull the hood release inside the cab, then release the safety latch at the front.
• Raise and secure the hood fully.

Step 2: Remove the upper headlamp fasteners

• Use a 10mm socket and ratchet to remove the upper mounting bolts for the headlamp housing.
• Keep the bolts in order so they go back in the same spots.

Step 3: Release the headlamp assembly

• Use a trim panel tool to gently release any retaining clips at the top edge.
• Pull the headlamp housing straight forward with both hands.
• Do not twist the housing.

Step 4: Disconnect the electrical connectors

• Use your hand to unplug the headlamp connector and any bulb connectors on the back of the housing.
• If a connector is tight, use a flat-blade screwdriver carefully to help lift the lock tab.

Step 5: Remove the old bulbs

• Twist each bulb socket or bulb assembly counterclockwise by hand, then pull it straight out.
• If your lamp uses HID bulbs, handle the bulb by the base only.
• Keep the bulb aligned during removal.

Step 6: Install the new bulbs

• Install the new bulb into the socket or housing using the same alignment as the old one.
• Twist clockwise by hand until it locks in place.
• Reconnect any electrical plugs until they click.

Step 7: Reinstall the headlamp assembly

• Slide the housing back into position by hand.
• Install the upper mounting bolts with a 10mm socket and ratchet.
• Torque to 4 Nm (35 in-lbs).

Step 8: Test the lights

• Turn the ignition on and switch the headlights on.
• Check both sides for low beam operation and proper aim.
• If one side does not work, recheck the connector and bulb seating.
