How to Install LED Fog Lights on Your Toyota Tundra (DIY Weekend Upgrade)

One of the easiest ways to transform your Tundra’s nighttime visibility—both on the highway and on dirt—is upgrading to LED fog lights. The factory halogens just don’t cut it, especially in bad weather. A fog light swap is one of the cleanest, fastest DIY installs you can do, and the difference is immediately noticeable the moment you turn them on.

Today we’re walking through how to install LED fogs, which brands perform best, and how to get a clean, OEM-plus look using parts available right now on TundraLifestyle.com.

Tools You’ll Need

• Phillips screwdriver

• 10mm socket + ratchet

• Trim removal tool or flat plastic pry tool

• Optional: work light or headlamp

• Optional: dielectric grease for long-term connection health

Step-by-Step Tundra Fog Light Installation

1. Turn the Wheel for Access

To reach the fog light assemblies easily:

• Turn your front wheels to the left to access the passenger fog

• Turn them to the right for the driver side

This opens up the splash liner area without needing to remove the wheel.

2. Remove the Fender Liner Clips

Use a trim tool to pop out:

• 2–3 plastic clips holding the inner liner

• Gently pull back the liner for access

No need to remove the entire liner—just enough to reach behind the fog light housing.

3. Unplug the Factory Fog Light Connector

Twist the bulb or housing (depending on your Tundra year) and disconnect the factory harness.

Tip:

If the connector feels stiff, press the tab firmly and wiggle gently. Don’t force it.

4. Remove the OEM Fog Light Housing

Depending on your year, remove:

• Two 10mm bolts

  or

• Phillips screws securing the fog light bracket

Set the OEM housing aside.

5. Install the New LED Fog Light

Mount your new LED fog light housing using the factory hardware.

Most premium models (Diode Dynamics, Morimoto, AlphaRex) are direct swap, no adapters needed.

Ensure:

• The housing is oriented correctly

• The beam cutoff is level

• The wiring faces upward for best moisture resistance

6. Connect the Plug-and-Play Harness

Plug your Tundra’s factory connector directly into the new LED fog light.

Optional but recommended:

Apply a small dab of dielectric grease to prevent moisture corrosion long-term.

7. Test Before Reassembling

Turn on your fog lights:

• Verify both sides illuminate

• Check for flicker or poor connection

• Confirm a clean, even cutoff pattern

Once satisfied, reinstall your splash liner clips.

Entire install typically takes 20–30 minutes.

Why LED Fogs Are Worth the Upgrade

✔ Massive improvement in visibility

Sharper, wider, brighter beam patterns—especially in fog, snow, or heavy rain.

✔ Instant OEM+ transformation

Upgraded LED color temperature modernizes the Tundra front end.

✔ Lower power draw, longer life

LED housings last significantly longer than halogens and draw less current.

✔ No wiring headaches

The premium brands we carry are 100% plug-and-play for the Tundra.
