🔨 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 move the safety latch under the front edge of the hood.
• Raise the hood and secure it with the hood prop rod.
• Use a flashlight to look behind the driver-side headlight housing.

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

• Use the flashlight to find the round rear of the low-beam bulb in the headlight housing.
• The H11 low-beam bulb has a plastic connector plugged into the back of it.
• Take a photo before unplugging.

Step 3: Unplug the Driver-Side Bulb Connector

• Use your fingers to press the release tab on the connector.
• Pull the connector straight back off the bulb.
• If the connector is stuck, use a small flat-blade screwdriver to gently lift the lock tab while pulling the connector back.
• Do not pull on the wires.

Step 4: Remove the Driver-Side Bulb

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

Step 5: Install the New Driver-Side Bulb

• Use nitrile gloves to remove one new H11 low-beam headlight bulb from the package.
• Hold the bulb only by the plastic base.
• If you accidentally touch the glass, use a clean microfiber towel to wipe it clean.
• Line up the bulb tabs with the slots in the headlight housing.
• Push the bulb straight in, then turn it clockwise until it locks firmly.
• Do not force it. If it does not seat flat, remove it and realign the tabs.

Step 6: Reconnect the Driver-Side Bulb Connector

• Use your hand to push the connector straight onto the new bulb.
• Listen or feel for the connector click into place.
• Lightly tug the connector by the plastic body to confirm it is locked.

Step 7: Replace the Passenger-Side Low-Beam Bulb

• Use the flashlight to locate the passenger-side low-beam bulb behind the headlight housing.
• Use your fingers to press the connector release tab and unplug the connector.
• If needed, use a small flat-blade screwdriver to gently help release the connector tab.
• Use your gloved hand to turn the bulb counterclockwise about a quarter turn.
• Pull the old bulb straight out.
• Install the second new H11 low-beam headlight bulb by lining up the tabs, pushing it in, and turning clockwise until locked.
• Use your hand to reconnect the electrical connector until it clicks.

Step 8: Test the Headlights

• Use your hand to turn the headlight switch on.
• Stand in front of your Tacoma and confirm both low beams work.
• Switch the headlights off after testing.
• If one side does not work, use your hand to check that the connector is fully clicked onto the bulb.

Step 9: Check Bulb Seating

• Use the flashlight to inspect the back of each headlight housing.
• Make sure each bulb sits flat and is fully locked.
• A crooked bulb can cause poor beam pattern or moisture entry.
