Whether you're dealing with a burnt-out fog light or upgrading to a brighter LED solution, replacing fog light bulbs is a simple but essential task. Fog lights enhance visibility during poor weather and make your vehicle more noticeable to others, so keeping them in good working condition is critical for safe driving.

This step-by-step guide from SEALIGHT will walk you through the replacement process. Whether you're a seasoned DIYer or a first-time car owner, you'll find this process approachable and easy to follow.

Step 1: Park and Prepare Your Vehicle

Begin by parking your vehicle on a flat surface and turning off the engine. Make sure the headlights and fog lights are switched off and give the fog light area time to cool down if it was recently used. Open the hood if necessary and gather your tools.

What you may need:

• A screwdriver or socket wrench (usually 10mm)
  
• A plastic clip remover
  
• Your new fog light bulb (Shop new LED fog bulbs at SEALIGHT)
  
• A microfiber towel and cleaning spray (optional)

Step 2: Locate and Access the Fog Light Housing

Fog light housings are typically located low on the front bumper. Depending on your vehicle, access may require removing a protective panel, wheel well liner, or plastic splash shield. Use a screwdriver or clip remover to take off any covers that block access to the fog light.

Once you have access, locate the back of the fog light housing and identify the electrical connector and bulb socket.

Step 3: Disconnect and Remove the Old Bulb

Unplug the electrical connector by pressing the release tab and gently pulling it off. Next, twist the bulb counterclockwise to release it from the socket and carefully pull it out.

Tip: If you’re replacing a full fog light assembly instead of just the bulb, additional clips or fasteners may need to be released before the housing can be removed.

Step 4: Clean the Area (Optional but Recommended)

Before installing the new bulb, it’s a good idea to clean around the housing using a microfiber towel and spray detailer. This removes any dirt or moisture and helps ensure the new bulb performs at its best.

Step 5: Install the New Fog Light Bulb

Take your new fog light bulb and line it up with the socket. Insert the bulb and twist it clockwise until it locks securely into place. Make sure the bulb is seated evenly to avoid misalignment or loose connections.

SEALIGHT LED fog light bulbs are designed for easy, plug-and-play installation, with a precise beam pattern that improves both visibility and appearance.

Step 6: Reconnect the Wiring

Plug the electrical connector back into the base of the new bulb. You should hear or feel a soft click when it connects properly. Gently tug the connector to confirm it’s locked in.

Step 7: Test the Fog Lights

Turn on your vehicle and activate the fog lights to ensure everything is functioning correctly. The new bulbs should light up instantly and produce a bright, focused beam.

If one or both lights do not turn on, double-check the connection and confirm the bulb is seated correctly.

Step 8: Reinstall Covers and Panels

Once the new fog light bulbs are tested and working, replace any panels or covers you removed during the installation process. Ensure all fasteners and clips are secure to prevent rattling while driving.
