Brake Light Bulb Replacement Steps

Accessing the Bulb

1. Open the rear hatch of your Forester.

4. Gently pull the tail light assembly away from the vehicle body.

Removing the Old Bulb

1. Identify the brake light bulb socket (usually the top one).

2. Turn the socket counterclockwise to unlock it.

3. Pull the socket out of the tail light assembly.

4. Remove the old bulb by pulling it straight out of the socket.

Installing the New Bulb

1. Insert the new 7443 bulb into the socket.

2. Ensure the bulb is firmly seated and oriented correctly.

3. Reinsert the socket into the tail light assembly.
