🔧 Outback - Left and Right Tail/Brake Light Bulb Replacement

Assumption: This procedure replaces the left and right dual-filament tail/brake bulbs, not the turn-signal or reverse bulbs.

Each rear combination lamp is serviced through an access cover inside the cargo area. Replace both bulbs together so their color and brightness match.

Difficulty Level: Beginner | Estimated Time: 15-30 minutes

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Left Lamp Access Cover

• Put on the safety glasses and nitrile mechanic gloves.
• Locate the small lamp-service cover in the left cargo-side trim, directly behind the rear combination lamp.
• Use the small plastic trim-removal tool at the cover notch and carefully pry the cover open.
• A trim-removal tool is a thin plastic lever that releases panels without scratching them.
• Do not bend the cover farther than necessary.

Step 2: Identify the Left Tail/Brake Bulb Socket

• Use the nitrile mechanic gloves to locate the tail/brake bulb socket through the opening.
• Select the socket for the dual-filament tail/brake bulb. Do not remove the turn-signal or reverse-light socket.
• The correct bulb has two electrical filaments and operates as both the dim tail lamp and bright brake lamp.

Step 3: Remove the Left Bulb

• Grip the socket with the nitrile mechanic gloves.
• Turn the socket counterclockwise approximately one-quarter turn, then pull it straight out of the lamp housing.
• Pull the old 7443 bulb straight out of the socket. Do not twist the bulb.
• No fasteners are removed, so no torque specification applies.

Step 4: Install the New Left Bulb

• Using the nitrile mechanic gloves, align the new 7443 bulb with the socket and press it straight in until fully seated.
• If the glass is accidentally touched, clean it with the clean microfiber cloth before installation.
• Insert the socket into the lamp housing and turn it clockwise until it stops securely.
• Never force a bulb or socket into place.

Step 5: Replace the Right Bulb

• Move to the right cargo-side trim and use the small plastic trim-removal tool to open its lamp-service cover.
• Using the nitrile mechanic gloves, turn the tail/brake bulb socket counterclockwise and remove it.
• Pull the old bulb straight out. Press the second new 7443 bulb fully into the socket.
• Reinstall the socket and turn it clockwise until secure.
• No fasteners are removed, so no torque specification applies.

Step 6: Refit the Access Covers

• Use the nitrile mechanic gloves to align each access cover with its opening.
• Press around each cover by hand until every retaining tab sits flush with the cargo trim.
• Use the small plastic trim-removal tool only if a cover edge needs gentle alignment.
