🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open hood and locate the turn signal area

• 🔸With the hood open, stand in front of the RAV4 and look at one headlight.
• 🔸The front turn signal bulb sits at the outer corner of the headlight (toward the fender).
• 🔸From behind the headlight, use your flashlight to find a small bulb socket near that outer corner; that is the turn signal socket.

Step 2: Gain access by moving the air inlet duct (left side)

• 🔸On the driver side, a plastic air inlet duct may block your hand.
• 🔸Use the flat trim removal tool to gently lift any plastic push clips on the duct or nearby cover.
• 🔸Use the 10mm socket with ratchet and extension to remove the small duct bolt if present.
• 🔸Lift or swing the duct slightly out of the way to create room for your hand. Do not force hard plastic.
• 🔸If you remove a 10mm bolt, when reinstalling later, tighten it to 5 Nm (44 in-lbs, about 3.7 ft-lbs).

Step 3: Remove the turn signal bulb socket

• 🔸Reach behind the headlight and grab the turn signal socket (round plastic piece with wires attached).
• 🔸Use your gloved hand to twist the socket about a quarter-turn counterclockwise.
• 🔸Pull the socket straight out of the headlight housing.
• 🔸If it feels stuck, gently wiggle while twisting—do not pry with tools on the housing.

Step 4: Remove the old bulb

• 🔸Hold the socket with one hand and grasp the bulb base with your other hand.
• 🔸Pull the bulb straight out of the socket. It is just a push-in (wedge) style.
• 🔸If needed, use a small flathead screwdriver very gently at the base to help lift the bulb—avoid damaging the plastic socket.

Step 5: Install the new bulb

• 🔸Before touching the glass, put on gloves or hold the bulb with a clean tissue.
• 🔸Apply a tiny dab of dielectric grease to the bulb’s metal contacts if available. Prevents corrosion.
• 🔸Push the new 7440 amber bulb straight into the socket until fully seated.
• 🔸Make sure it feels snug; a loose bulb can lose connection while driving.

Step 6: Reinstall the bulb socket into the headlight

• 🔸Align the tabs on the bulb socket with the slots in the headlight opening.
• 🔸Insert the socket straight in until it sits flush.
• 🔸Twist the socket clockwise about a quarter-turn with your gloved hand until it stops.
• 🔸There are no bolts here, so no torque spec is needed; just hand-tight until fully locked.

Step 7: Repeat for the other side

• 🔸Move to the passenger side and repeat Steps 1–6.
• 🔸On this side, you may have more or less room depending on harness routing; use your flashlight to see the socket clearly.
• 🔸Always replace both front bulbs together so brightness and color match.

Step 8: Reinstall any air duct and clips

• 🔸Reposition the air inlet duct and any covers you moved out of the way.
• 🔸Insert plastic push clips by hand; push the center pins down to lock.
• 🔸Reinstall any removed bolt using the 10mm socket and ratchet.
• 🔸Tighten the bolt to 5 Nm (44 in-lbs, about 3.7 ft-lbs)—snug but not hard, to avoid cracking plastic.

Step 9: Test the turn signals

• 🔸Sit in the driver seat and turn the ignition to ON (engine can stay off).
• 🔸Operate the left turn signal and walk to the front to check the bulb.
• 🔸Then operate the right turn signal and check that bulb.
• 🔸Confirm they flash at a normal speed; extremely fast flashing usually means a bulb is not working or not seated correctly.

✅ After Repair

• 🔸Verify both front and rear turn signals work on left and right sides.
• 🔸Check the hazard lights; all four corners should flash normally.
• 🔸Make sure the headlight housings are fully sealed with sockets locked in place (no gaps).
• 🔸Dispose of old bulbs properly—do not leave them in the engine bay.
