📋 Before You Begin

• Park the RAV4 on level ground, shift to Park, and set the parking brake.
• Turn off the headlights and hazard lights, and remove the key from the ignition.
• Open the hood and secure it with the prop rod.
• Make sure you have good lighting so you can see behind the headlight assemblies.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open hood and create access

• Open the hood and prop it up securely.
• On top of the grille area you may see a plastic cover with push clips.
• If it blocks your hand access, use the flathead screwdriver to gently lift the center pins of the plastic clips and remove the cover. Only remove if truly in your way

Step 2: Locate the front turn signal bulb socket

• Standing in front of the RAV4, look behind the headlight on the driver side from under the hood.
• The front turn signal bulb is the socket toward the outer side of the headlight (closest to the fender).
• It is usually a gray or black plastic socket with two wires going into it.
• Use the work light or flashlight to clearly see the socket and wiring.

Step 3: Remove the driver-side bulb socket

• Reach behind the headlight and grab the turn signal socket body, not the wires.
• Twist the socket about a quarter turn (usually counterclockwise) to unlock it.
• Carefully pull the socket straight out of the headlight housing.
• If tight, wiggle gently—do not force or twist wires

Step 4: Remove the old bulb from the socket

• Hold the socket in one hand and the bulb base in the other.
• Pull the bulb straight out of the socket; it is a push-in type.
• If it feels stuck, rock it slightly side to side while pulling.

Step 5: Prepare the new bulb

• Use the clean lint-free cloth to handle the new bulb, or wear mechanic gloves.
• If you accidentally touch the glass, clean it with an alcohol wipe and let it dry.
• Apply a very small dab of dielectric grease to the bulb’s metal contacts where it plugs into the socket. This helps prevent corrosion

Step 6: Install the new driver-side bulb

• Push the new 7440 amber bulb firmly straight into the socket until fully seated.
• Make sure it is straight and not loose.

Step 7: Reinstall the driver-side socket into headlight

• Align the tabs on the socket with the slots in the headlight housing.
• Insert the socket fully into the opening.
• Twist the socket about a quarter turn (usually clockwise) until it stops and feels locked.
• If it doesn’t seat, remove and re-align the tabs

Step 8: Repeat removal and installation on passenger side

• Move to the passenger side and repeat Steps 2–7.
• On this side, you may have slightly less room due to the battery.
• If needed for a bit more space, you can loosen the front battery clamp bolt using a 10mm socket and ratchet just enough to slide the battery slightly backward. Do not disconnect the cables.
• When finished, move the battery back to its original spot and snug the clamp bolt with the 10mm socket. Torque to snug only (about hand-tight + 1/4 turn)

Step 9: Reinstall any covers or clips

• If you removed the plastic upper cover, position it back in place.
• Reinstall the plastic clips by pushing the outer body in first, then pressing the center pin down flush.
• Replace any broken clips with new ones from your parts list.

✅ After Repair

• Turn the ignition to ON (engine can be off) and activate the left and right turn signals to check that both new bulbs flash normally.
• Turn on the hazard lights and walk around the front of the RAV4 to confirm both front turn signals are working and are similar brightness and color.
• Check the instrument panel; ensure there is no rapid blinking, which would indicate a bad connection or bulb.
• Close the hood securely and make a short test drive, using both turn signals to confirm normal operation.
