⚠️ Safety & Precautions

• 🔸Turn the ignition OFF and remove the key so lights cannot turn on while you work.
• 🔸Let the bulbs cool before touching them; they can be very hot right after use.
• 🔸Do not touch the glass of new bulbs with bare fingers; skin oils can shorten bulb life.
• 🔸Work in a well-lit, stable area so you don’t trip or bump the open tailgate.
• 🔸Battery disconnect is not required for this job.

📋 Before You Begin

• Park your CR-V on level ground, shift to P, and set the parking brake.

• Turn off all lights and confirm the turn signals are off.
• Gather tools and parts behind the vehicle so you don’t need to walk away mid-job.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the rear side trim panel

• Stand at the rear of your CR-V with the tailgate open and look at the side wall trim, directly behind each tail light.
• Use the plastic trim removal tool to gently pry open the small rectangular access cover in the interior trim (behind the tail light area).
• If the cover is tight, you can carefully use the small flathead screwdriver, wrapped with a clean shop towel to avoid scratching the plastic.
• Torque spec: No fasteners are removed in this step.

Step 2: Locate the turn signal bulb socket

• Look through the opening behind the tail light. You’ll see several bulb sockets inserted into the rear of the housing.
• The rear turn signal socket is usually the middle or lower socket with colored (often green or brown) wiring; it holds an amber 7440 bulb.
• Compare to the new bulb location to be sure.
• Torque spec: No fasteners are removed in this step.

Step 3: Remove the turn signal bulb socket

• Grip the turn signal socket firmly with your hand through the access opening.
• Turn the socket about a quarter turn counterclockwise by hand to unlock it.
• Pull the socket straight out from the tail light housing.
• If stuck, wiggle gently; do not pry.
• Tool used: Hands only, no tool needed here.
• Torque spec: Socket is twist-lock only; no torque value.

Step 4: Remove the old bulb from the socket

• Hold the socket in one hand. With the other hand, grasp the glass part of the bulb using mechanic gloves or a clean shop towel if hot or slippery.
• Pull the bulb straight out of the socket. It may feel snug but should come out with steady pull.
• If it’s very tight, gently wiggle the bulb as you pull.
• Torque spec: Not applicable for this step.

Step 5: Install the new bulb

• Before installing, apply a tiny dab of dielectric grease to the bulb’s metal contacts. This helps prevent corrosion.
• Holding the new 7440 amber bulb with a clean shop towel (to avoid skin oil), align the metal base with the socket.
• Push the bulb straight into the socket until it seats firmly.
• If it feels loose, remove and reseat.
• Torque spec: Push-fit only; no torque value.

Step 6: Reinstall the bulb socket into the tail light

• Guide the socket with the new bulb back into the opening in the tail light housing.
• Align the tabs on the socket with the slots in the housing.
• Push the socket in fully, then turn it clockwise about a quarter turn until it stops and feels locked.
• Do not force; back off and realign if it won’t turn.
• Tool used: Hands only.
• Torque spec: Twist until snug; no specific torque.

Step 7: Test the new bulb

• Leave the interior access panel still open for now.
• Close the tailgate enough that the tail lights are visible to someone standing behind.
• Turn the ignition to ON (engine can stay off) and use the turn signal stalk to signal left or right, depending on which side you replaced.
• Check that the new bulb flashes at normal speed and brightness.
• If it does not light, reseat the bulb in the socket.
• Torque spec: Not applicable.

Step 8: Reinstall the interior access cover

• Turn the ignition OFF again.
• Align the plastic access cover tabs with the opening in the interior trim.
• Press the cover in firmly by hand until it clicks and sits flush with the trim.
• Use your fingers or the plastic trim removal tool if needed to fully seat any edges.
• Torque spec: Snap-fit only; no torque value.

Step 9: Repeat on the other side

• Repeat Steps 1–8 on the other rear turn signal. It’s best to replace bulbs in pairs so brightness and color match.
• Torque spec: Same as previous steps; no torqued fasteners.
