⚠️ Safety & Precautions

• Turn the headlight switch off and remove the key/fob from the vehicle.
• Let the bulbs cool before touching the housing. Halogen bulbs get very hot.
• Do not touch the glass part of a new halogen bulb with bare fingers. Skin oil shortens bulb life.
• If your truck has projector-style lamps, be gentle with the rear dust cap and wiring.
• No battery disconnect is required for this repair.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the back of the headlamp

• Open the hood and locate the rear of the headlight housing.
• If anything blocks access, use the 8mm socket and 1/4-inch ratchet to remove the air intake tube fasteners or nearby cover pieces, if equipped.
• Move wiring and the intake tube gently out of the way.

Step 2: Remove the bulb connector

• Reach behind the headlamp and unplug the electrical connector from the bulb.
• If the connector is tight, use your fingers and a small wiggle motion. Do not pull on the wires.
• Pull on the plug, not the wires.

Step 3: Remove the old bulb

• Rotate the bulb counterclockwise by hand until it unlocks.
• Pull the bulb straight out of the housing.
• Inspect the rubber seal and housing opening for dirt or moisture.

Step 4: Install the new bulb

• Put on mechanic gloves before handling the new bulb.
• Insert the new bulb into the housing in the same position as the old one.
• Rotate it clockwise by hand until it locks in place.
• Reconnect the electrical connector until it clicks.

Step 5: Reassemble the intake or cover pieces

• Reinstall any intake duct or cover pieces removed earlier.
• Use the 8mm socket and 1/4-inch ratchet to tighten fasteners snugly.
• Torque to 8 Nm (71 in-lbs) for small plastic trim fasteners, if equipped.

Step 6: Repeat on the other side

• Follow the same steps for the opposite headlight bulb.
• Make sure both bulbs are fully seated and the connectors are locked.
