đź”§ Impreza - Front Turn Signal Bulb Replacement

On your Impreza, the front turn signal is typically a replaceable amber bulb inside the headlight housing. The job is done from behind the headlight (from the engine bay) by removing the turn-signal socket and swapping the bulb.

Difficulty Level: Beginner | Estimated Time: 0.3-0.7 hours


⚠️ Safety & Precautions

  • ⚠️ Turn the lights OFF and remove the key before starting.
  • ⚠️ Let the headlight area cool if you were just driving (hot plastic and bulbs).
  • ⚠️ Don’t touch the new bulb’s glass with bare fingers; skin oil can shorten bulb life.
  • ⚠️ No battery disconnect is required for this repair.

đź”§ Required Tools

You'll need the following tools for this repair:

  • Nitrile gloves
  • Safety glasses
  • Small flathead screwdriver
  • Flashlight

🔩 Required Parts

  • Front turn signal bulb (amber) - Replace in pairs - Qty: 2

đź“‹ Before You Begin

  • Park on level ground and set the parking brake.
  • Turn the steering wheel straight and pop the hood.
  • Have your flashlight ready so you can see behind the headlight.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm you’re replacing the correct bulb

  • Turn the hazard lights ON briefly, then OFF (use the hazard button).
  • Verify the front turn signal on the side you’re working on is the one that’s out or blinking fast.

Step 2: Access the turn signal socket behind the headlight

  • Open the hood and stand behind the headlight on the side you’re replacing.
  • Use a flashlight to locate the turn signal socket (a twist-lock socket going into the back of the headlight housing).
  • If an intake snorkel/cover is blocking your hand, gently release its plastic clips using a small flathead screwdriver and move it slightly for access. Only move what you must.

Step 3: Remove the turn signal bulb socket

  • Put on nitrile gloves and safety glasses.
  • Grip the socket and rotate it about 1/4 turn counterclockwise by hand, then pull it straight out.
  • If it feels stuck, wiggle gently while turning—don’t force the headlight housing.

Step 4: Replace the bulb

  • Pull the old bulb straight out of the socket (it’s a push-in style).
  • Install the new amber bulb by pushing it straight into the socket until fully seated.
  • A “twist-lock socket” means the socket seals by turning; don’t cross-thread or jam it.

Step 5: Reinstall the socket

  • Insert the socket back into the headlight opening, keeping it aligned.
  • Turn the socket clockwise about 1/4 turn until it stops (snug by hand).
  • Reinstall any snorkel/cover clips you moved using the small flathead screwdriver.

Step 6: Repeat on the other side (recommended)

  • Replace the bulb on the other front turn signal as well so color and brightness match.

âś… After Repair

  • Turn the hazard lights ON and confirm both front turn signals flash normally.
  • Turn the left and right signals ON from inside and verify the dash indicator flashes at a normal speed.
  • If it still “hyper-flashes” (blinks fast), the bulb may not be seated, or another turn signal bulb may be out.

Quick check (so I don’t steer you wrong):

  • âť“ Do your headlights have a regular replaceable bulb (halogen) or are they factory LED headlights?
  • âť“ When the turn signal is ON, is the front turn signal completely out, or is it blinking fast (“hyper-flash”)?
