⚠️ Safety & Precautions

• 🛑 Turn the engine off, remove the key, and let the engine bay cool before working near the headlights.
• 🧤 Avoid touching the glass of any bulb with bare fingers; oils can shorten bulb life.
• 🔋 Battery disconnect is not required, but do not work on the bulbs with the hazard lights or blinkers turned on.
• 👀 Work in good lighting so you can clearly see the bulb sockets and wiring.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the upper radiator cover for easier access

• The upper radiator cover is the plastic panel running across the front, just behind the grille.
• Use the trim clip removal tool to gently pry up the center pins of the plastic clips along the top of the cover.
• If needed, use a flathead screwdriver carefully under the clip centers to pop them up. Twist, don’t pry straight up
• Once the centers are up, pull the clips out and lift the plastic cover off. Set it aside.

Step 2: Create room behind the headlight

• You’ll be working from behind each headlight assembly, inside the engine bay.
• On the driver side, if space is tight, you can remove the top headlight mounting bolt to tilt the headlight slightly:
• Use a 10mm socket, extension, and ratchet to remove the upper headlight bolt.
• Keep the bolt somewhere safe; you will reinstall it later. Torque to 7 Nm (62 in-lbs) on reassembly.
• You do not need to fully remove the headlight; just create a bit more wiggle room if needed.

Step 3: Locate the front turn signal bulb socket

• Stand in front of the Tacoma and look at the headlight: the front turn signal is the amber section near the outer corner of the headlight housing.
• From inside the engine bay, reach behind the headlight and look for a circular bulb socket with two wires going into it, positioned behind that outer amber area.
• The socket will usually be gray or black plastic, about the size of a large coin.

Step 4: Remove the bulb socket

• Grip the bulb socket firmly by hand.
• Turn the socket about a quarter-turn counterclockwise to unlock it from the headlight housing.
• Pull the socket straight back to remove it from the headlight.
• If it’s stuck, wiggle gently while turning

Step 5: Remove the old bulb

• Hold the socket with the bulb pointing upward so it doesn’t fall.
• Pull the bulb straight out from the socket. Most Tacoma front turn signal bulbs are simple “wedge” style and just slide out.
• If it feels tight, gently rock the bulb side to side while pulling.

Step 6: Prepare the new bulb

• Take a new front turn signal bulb (7444NA or 7440 amber) out of its package.
• Use a shop towel or clean microfiber cloth to hold the new bulb so you don’t touch the glass.
• Apply a small dab of dielectric grease to the bulb’s metal contacts where it plugs into the socket. This helps prevent corrosion.

Step 7: Install the new bulb into the socket

• Align the base of the new bulb with the slot in the socket.
• Push the bulb straight into the socket firmly until it seats fully.
• Check that the bulb is straight and not loose. A loose bulb can flicker

Step 8: Reinstall the bulb socket into the headlight

• Guide the bulb and socket back into the opening in the rear of the headlight housing.
• Make sure the bulb goes fully into the housing and the socket tabs align with the slots.
• Turn the socket about a quarter-turn clockwise until it stops. This locks it in place; hand-tight only, no tools.

Step 9: Repeat on the other side

• Repeat Steps 3–8 for the opposite headlight so both front turn signals are new and match in brightness and color.

Step 10: Reinstall any removed bolts and the upper radiator cover

• If you removed a headlight upper bolt, reinstall it now:
• Use the 10mm socket, extension, and ratchet to tighten the bolt.
• Torque to 7 Nm (62 in-lbs) — snug, not very tight.
• Place the upper radiator cover back in position.
• Insert each plastic clip, then push down the center pin to lock it in place. If any clips broke, replace them with new ones.

✅ After Repair

• Turn the ignition to ON (engine can be off) and switch on the left turn signal. Walk to the front and confirm the left front turn signal is flashing normally.
• Repeat for the right turn signal.
• Turn on the hazard lights and confirm both front signals flash at the same rate and brightness.
• If one side flashes very fast, the bulb may not be seated correctly; turn everything off and reseat that bulb.
