🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the Rear Lamp Bolts

• Put on the safety glasses and nitrile gloves.
• Find the two mounting bolts on the inside edge of the rear lamp, exposed when the liftgate is open.
• Use the 8mm socket and 1/4-inch drive ratchet to remove both bolts.
• Keep the bolts in a safe place.

Step 2: Release the Lamp Assembly

• Hold the lamp with both hands and pull it straight rearward, parallel with the side of your HR-V.
• If it is tight, use the plastic trim removal tool gently along the outer edge while pulling rearward.
• Do not pry against the painted edge or pull the lamp sideways; alignment pins hold its outer side.
• Gentle rocking helps release stubborn alignment pins.

Step 3: Remove the Turn Signal Socket

• Support the loose lamp assembly with one hand so the wiring remains relaxed.
• Locate the socket behind the amber turn-signal section of the lamp.
• Turn the socket counterclockwise by hand about one-quarter turn, then pull it straight out.
• A socket is the plastic holder that supplies power to the bulb.

Step 4: Replace the Bulb

• Use your gloved fingers to pull the old bulb straight out of the socket; do not twist it.
• Compare the new 7440A amber bulb with the removed bulb. Their wedge-shaped bases must match.
• Push the new bulb straight into the socket until fully seated.
• Use the microfiber cleaning cloth to wipe away fingerprints from the bulb.

Step 5: Test the New Bulb

• Keep the lamp supported and make sure the bulb socket cannot touch painted bodywork.
• Switch on the ignition and operate the corresponding turn signal.
• Confirm the new bulb flashes brightly and at the normal speed, then switch the ignition and lights off.
• If it does not work, remove the bulb and use your gloved fingers to reseat it firmly.

Step 6: Reinstall the Bulb Socket

• Insert the socket into the lamp with its tabs aligned.
• Turn the socket clockwise by hand until it locks securely.
• Check that the socket seal sits evenly so moisture cannot enter the lamp.

Step 7: Reinstall the Lamp Assembly

• Align the lamp's outer locating pins with their body-mounted grommets.
• Press the lamp straight forward by hand until it sits evenly against the body.
• Start both mounting bolts by hand to prevent cross-threading.
• Use the 8mm socket and 1/4-inch drive torque wrench to tighten the bolts to 5 Nm (44 in-lbs).
• Do not overtighten the bolts; excessive force can crack the plastic lamp housing.

Step 8: Repeat on the Opposite Side

• Use the same 8mm socket, 1/4-inch drive ratchet, and plastic trim removal tool to replace the opposite rear turn signal bulb.
• Replacing both bulbs together helps maintain equal brightness and reduces the chance of another bulb failing soon.

✅ After Repair

• ✅ Operate the left and right turn signals and confirm both rear bulbs flash normally.
• 🚨 Switch on the hazard lights and inspect both lamps again.
• 🔍 Confirm each lamp sits flush and does not move when gently pressed.
• 💧 After the next wash or rain, check that no condensation has entered the lamp.
• 📱 No warning-light reset, coding, or scan-tool procedure is needed.
