🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Tailgate

• Use your hands to lower the tailgate completely.
• Look at the inside edge of the tail lamp. You will see two retaining bolts.
• Keep one hand on the lamp later.

Step 2: Remove the Tail Lamp Bolts

• Use a 10mm socket and 1/4-inch drive ratchet to remove the two tail lamp bolts.
• Set the bolts in a safe place so they do not fall into the bed gap.

Step 3: Pull the Tail Lamp Straight Rearward

• Hold the tail lamp with both hands.
• Pull the lamp straight back toward the rear of your Tacoma.
• If it feels stuck, use a plastic trim tool gently at the outer edge to help release the locating pins.
• Do not twist the lamp sharply. The wiring is still attached.
• Plastic trim tools prevent paint scratches.

Step 4: Identify the Rear Turn Signal Bulb Socket

• Look at the back of the tail lamp assembly.
• The rear turn signal bulb socket is the socket for the amber turn signal bulb.
• A socket here means the plastic bulb holder that twists into the lamp housing.

Step 5: Remove the Bulb Socket

• Use your hand to turn the rear turn signal bulb socket counterclockwise about a quarter turn.
• Pull the socket straight out of the tail lamp housing.
• Do not pull on the wires.

Step 6: Replace the Bulb

• Use your gloved hand to pull the old bulb straight out of the socket.
• Push the new rear turn signal bulb straight into the socket until fully seated.
• If using a glass bulb, avoid touching the glass with bare fingers.
• Match the old bulb shape before installing.

Step 7: Reinstall the Bulb Socket

• Use your hand to insert the socket back into the tail lamp housing.
• Turn the socket clockwise until it locks in place.
• Make sure the socket sits flat and secure.

Step 8: Test the Turn Signal

• Use your hand to turn the ignition key to ON, but do not start the engine.
• Turn on the left or right turn signal for the side you repaired.
• Confirm the new rear turn signal bulb flashes normally.
• Turn the ignition and turn signal off after testing.

Step 9: Reinstall the Tail Lamp Assembly

• Use your hands to align the locating pins on the tail lamp with the body openings.
• Push the lamp straight forward until it seats against the bedside.
• Use a 10mm socket and 1/4-inch drive ratchet to reinstall the two bolts.
• Tighten the bolts snugly by hand with the ratchet. Do not overtighten, because the lamp housing can crack.
• Torque to 5 Nm (44 in-lbs)

Step 10: Final Check

• Use your hand to turn on the turn signal again.
• Confirm the rear bulb flashes at the same speed as the front bulb.
• Close the tailgate once everything works correctly.
