🔧 Forte - Rear Turn Signal Bulb Replacement

Your Forte’s rear turn signal bulbs sit in the tail lamp housings and can be replaced from inside the trunk. You’ll remove a small trunk trim access cover, twist the bulb socket out, then swap the bulb.

Difficulty Level: Beginner | Estimated Time: 0.3-0.8 hours


⚠️ Safety & Precautions

  • ⚠️ Turn the ignition OFF and remove the key/fob from the car.
  • ⚠️ Let bulbs cool before touching; they can be very hot.
  • ⚠️ Don’t touch the glass on incandescent bulbs; skin oil can shorten bulb life.

🔧 Required Tools

You'll need the following tools for this repair:

  • Trim clip removal tool
  • Small flathead screwdriver
  • Nitrile gloves
  • Safety glasses
  • Flashlight

🔩 Required Parts

HowToo sells all the parts you need for this repair:

  • Rear turn signal bulb (match the bulb number printed on your old bulb) - Qty: 2

📋 Before You Begin

  • Park on level ground and set the parking brake.
  • Open the trunk and clear out cargo so you can work safely.
  • Tip: Do one side at a time.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the tail lamp service opening

  • Open the trunk.
  • On the side you’re replacing, locate the small trim access door/cover behind the tail lamp area.
  • Use a trim clip removal tool to pop the cover open. If it’s tight, gently help it with a small flathead screwdriver.
  • Use a flashlight to see the bulb sockets clearly.

Step 2: Identify the turn signal bulb socket

  • Look for the socket that corresponds to the turn signal in the tail lamp (typically the amber section of the lens).
  • If you’re not sure which socket is which, turn the hazard lights ON briefly, then OFF, and watch which area flashes. (Keep hands clear of moving trunk hinges.)

Step 3: Remove the bulb socket

  • Grip the socket firmly and rotate it counterclockwise about 1/4 turn to unlock it.
  • Pull the socket straight out of the tail lamp housing.

Step 4: Replace the bulb

  • Pull the old bulb straight out of the socket (most rear turn bulbs are a wedge-base style).
  • Put on nitrile gloves and install the new bulb by pushing it straight into the socket until fully seated.
  • Tip: Match the old bulb’s number exactly.

Step 5: Reinstall the socket and trim cover

  • Insert the socket back into the tail lamp housing.
  • Rotate clockwise about 1/4 turn until it locks.
  • Reinstall the trunk access cover by pressing it back into place.

Step 6: Repeat on the other side (recommended)

  • Repeat Steps 1–5 for the opposite rear turn signal.
  • Tip: Replace bulbs in pairs for even brightness.

✅ After Repair

  • Turn the ignition ON and test left and right turn signals.
  • Turn on hazards and confirm both rear turn signals flash at a normal speed.
  • If a signal flashes fast, re-check that the bulb is fully seated and the correct type.
