🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Hood

• Use your hand to pull the hood release inside the cabin.
• Use your hand to release the safety latch at the front of the hood.
• Raise the hood and secure it with the prop rod.
• Use a flashlight to look behind each headlamp housing.

Step 2: Locate the Driver-Side Low-Beam Bulb

• Use a flashlight to find the low-beam bulb socket on the rear of the driver-side headlamp housing.
• The low-beam bulb is the H11 bulb installed in the projector-style low-beam section.
• Identify the electrical connector attached to the back of the bulb.
• Take a quick phone photo first.

Step 3: Disconnect the Driver-Side Bulb Connector

• Use your fingers to press the locking tab on the electrical connector.
• Pull the connector straight rearward off the bulb.
• If the connector is tight, gently wiggle it while pulling. Do not pull on the wires.

Step 4: Remove the Driver-Side Bulb

• Use your gloved hand to grip the bulb base.
• Rotate the bulb counterclockwise about a quarter turn.
• Pull the bulb straight out of the headlamp housing.
• No fasteners are used here, so there is no torque specification.

Step 5: Install the New Driver-Side Bulb

• Use nitrile gloves to handle the new H11 bulb by the plastic base only.
• Align the bulb tabs with the slots in the headlamp housing.
• Insert the bulb straight into the housing.
• Rotate the bulb clockwise until it locks in place.
• Use your fingers to reconnect the electrical connector until it clicks.
• Do not force the bulb tabs.

Step 6: Move Items for Passenger-Side Access

• Use a flashlight to inspect the space behind the passenger-side headlamp housing.
• If the intake duct blocks access, use a flat trim removal tool to lift the plastic push clips from the duct.
• Move the intake duct aside carefully by hand.
• A push clip is a reusable plastic fastener with a center pin that locks it into place.

Step 7: Disconnect the Passenger-Side Bulb Connector

• Use your fingers to press the locking tab on the passenger-side bulb connector.
• Pull the connector straight rearward off the bulb.
• If it is stuck, gently wiggle the connector while pulling on the connector body only.

Step 8: Remove the Passenger-Side Bulb

• Use your gloved hand to grip the bulb base.
• Rotate the bulb counterclockwise about a quarter turn.
• Pull the old bulb straight out of the headlamp housing.
• No fasteners are used here, so there is no torque specification.

Step 9: Install the New Passenger-Side Bulb

• Use nitrile gloves to handle the new H11 bulb by the plastic base only.
• Align the bulb tabs with the slots in the headlamp housing.
• Insert the bulb straight into the housing.
• Rotate the bulb clockwise until it locks in place.
• Use your fingers to reconnect the electrical connector until it clicks.

Step 10: Reinstall Any Moved Intake Duct Pieces

• Use your hands to place the intake duct back into its original position.
• Use your fingers to reinstall the plastic push clips.
• Press each clip down until it sits flush.
• No torque specification applies to the plastic push clips.

Step 11: Test the Headlights

• Use the headlight switch to turn the low beams on.
• Stand in front of your Altima and confirm both new bulbs turn on.
• Check that both beams look even and are not flickering.
• Turn the headlights back off when finished.
