Step-by-Step Guide to Replacing Your Brake Light Bulb
Open the Trunk: This gives you access to the rear light assembly.
Remove the Light Cover: Depending on the E46 variant, you may need to unscrew or pull off plastic clips.
Unplug the Wiring Harness: Gently pull the connector off the bulb socket.
Replace the Bulb: Twist the old bulb counterclockwise to remove it. Insert the new bulb by twisting it clockwise.
Reconnect the Wiring Harness: Ensure it clicks securely into place.
Test the Lights: Before reattaching any covers, test your new bulb by pressing the brake pedal to ensure it lights up properly.
Reassemble: Put everything back in reverse order, and you’re done!
Troubleshooting Brake Light Issues
If the warning light persists after replacing the bulb: This could indicate a blown fuse or a wiring issue. Check the fuse for the brake lights located in the fuse box under the dashboard.
If the bulb burns out quickly: Ensure you are not using a bulb with too high wattage, which can overheat and damage the light socket.
Intermittent lighting: Check for corrosion or loose connections in the wiring harness.
