🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Open the hood
- Pull the hood release inside the cabin, then open the hood and secure it.
- Work slowly around plastic clips.
Step 2: Locate the turn signal bulb socket
- Find the rear of the headlamp assembly for the front turn signal bulb.
- On your Prius C, the bulb is accessed from the engine bay, not from the wheel well.

- Use your hand or a small flat-blade screwdriver to gently pry off the rear access cap if it is tight.
- Set the cap aside where it stays clean.
Step 4: Remove the bulb socket
- Twist the bulb socket counterclockwise by hand and pull it straight out of the headlamp housing.
- Do not yank on the wiring.
Step 5: Replace the bulb
- Remove the old bulb from the socket.
- Install the new amber bulb firmly into the socket.
- If the bulb is a twist-lock style, align it correctly before inserting.
Step 6: Reinstall the socket and cover
- Insert the socket back into the headlamp housing and twist it clockwise until it locks.
- Reinstall the access cap fully so moisture stays out.
Step 7: Test the new bulb
- Turn the ignition ON and activate the turn signal.
- Confirm the front bulb flashes normally on both sides.
✅ After Repair
- Check both front turn signals for proper flash rate.
- Make sure the access cap is seated tightly.
- If the bulb does not work, remove it and confirm it is fully seated in the socket.
