📋 Before You Begin

• Park your RAV4 on level ground.
• Shift to Park and set the parking brake.
• Turn the power switch OFF and keep the key fob away from the vehicle.
• Open the liftgate fully.
• Wear clean gloves. Oil from your fingers can shorten bulb life.
• A plastic trim removal tool is a non-metal pry tool used to remove small covers without scratching paint or trim.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Liftgate and Locate the Tail Lamp Fasteners

• Open the rear liftgate all the way.
• Look at the inner edge of the tail lamp assembly on the side you are replacing.
• Use the plastic trim removal tool to gently pop off the small plastic access covers if equipped.
• You will see the tail lamp retaining bolts.
• Work slowly to avoid scratches.

Step 2: Remove the Tail Lamp Bolts

• Use the 10mm socket and 1/4-inch ratchet to remove the tail lamp bolts.
• Place the bolts somewhere safe so they do not fall into the cargo area.
• There is no torque needed during removal.

Step 3: Pull the Tail Lamp Assembly Straight Rearward

• Hold the tail lamp assembly with both hands.
• Pull it straight back away from the body of the RAV4.
• Do not twist it side to side. The lamp has guide pins that pull straight out.
• If it feels stuck, use the plastic trim removal tool carefully at the outer edge to help release it.
• Straight back prevents broken pins.

Step 4: Remove the Rear Turn Signal Bulb Socket

• Find the turn signal bulb socket on the back of the tail lamp assembly.
• The rear turn signal bulb is the amber flashing bulb location.
• Use your gloved hand to rotate the socket counterclockwise about a quarter turn.
• Pull the socket straight out of the lamp housing.

Step 5: Replace the Bulb

• Use clean nitrile gloves to pull the old bulb straight out of the socket.
• Push the new rear turn signal bulb straight into the socket until fully seated.
• Do not force it. The bulb should fit snugly.
• If the bulb has a wedge base, it pulls and pushes straight in.
• A wedge base bulb has a flat plastic/glass end that slides directly into the socket.

Step 6: Reinstall the Bulb Socket

• Insert the bulb socket back into the tail lamp housing.
• Use your gloved hand to rotate the socket clockwise until it locks.
• Make sure it sits flat and tight so water cannot enter the lamp.

Step 7: Test the Turn Signal Before Bolting the Lamp Back In

• Keep the tail lamp supported so it does not hang by the wiring.
• Turn the vehicle to accessory/ON mode without starting the hybrid system.
• Use the turn signal stalk to test the side you replaced.
• Confirm the rear bulb flashes normally.
• Turn the power switch OFF after the test.
• If it does not flash, remove the bulb with clean nitrile gloves and reseat it in the socket.

Step 8: Reinstall the Tail Lamp Assembly

• Line up the guide pins with the body openings.
• Push the tail lamp straight forward until it seats evenly against the body.
• Use the 10mm socket and 1/4-inch ratchet to reinstall the bolts.
• Torque to 5.0 Nm (44 in-lbs).
• If using hand feel only, snug the bolts gently. Do not overtighten.

Step 9: Reinstall Covers and Final Check

• Use your hand to snap any plastic access covers back into place.
• Close the liftgate.
• Turn the hazard lights on and confirm both rear turn signals flash normally.
