⚠️ Safety & Precautions

• ⚠️ Turn the ignition OFF and remove the key before working near the radiator fans and belts.
• ⚠️ If you raise the front end, support your Tundra with jack stands (never rely on a floor jack alone).
• ⚠️ Wear nitrile gloves; don’t touch the new bulb glass with bare fingers (skin oil can shorten bulb life).

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Verify the bulb you’re replacing

• Turn the hazards ON briefly, then OFF, to confirm which front side is out.
• Use nitrile gloves and a flashlight to look into the front lamp area.

Step 2: Choose your access method

• Method A (often easiest for beginners): Access through the wheel well liner.
• Method B: Access from under the hood if your hand fits behind the headlamp.

Step 3 (Method A): Raise the front corner (recommended)

• Place wheel chocks behind a rear tire.
• Use a floor jack (rated 3-ton minimum) to lift the front corner on the side you’re working on.
• Set the truck onto jack stands (rated 3-ton minimum).

Step 4 (Method A): Remove the front wheel for space (optional but helpful)

• Use a 21mm socket to remove the lug nuts and take the wheel off.
• When reinstalling later, Torque to 177 Nm (131 ft-lbs) using a torque wrench.

Step 5 (Method A): Open the fender liner access

• Use a trim clip removal tool and flat trim tool to pop out the plastic clips/splash shield retainers near the front of the wheel well.
• If a screw is present, remove it with a Phillips screwdriver.
• Pull the liner back just enough to reach behind the headlamp.

Step 6 (Method B): Create space under the hood (if needed)

• Open the hood and use a flashlight to locate the turn signal bulb socket at the rear of the headlamp assembly.
• If an intake snorkel cover blocks access, remove the bolts with a 10mm socket, 1/4" ratchet, and 6" extension, then move it aside.
• Tip: Don’t force your hand—use Method A.

Step 7: Remove the turn signal bulb socket

• Reach the bulb socket behind the headlamp and rotate it counterclockwise using your gloved hand.
• Pull the socket straight out.

Step 8: Replace the bulb

• Pull the old bulb straight out of the socket (no twisting on most wedge-base bulbs).
• Push the new bulb straight in until fully seated.
• Keep using nitrile gloves so you don’t touch the bulb glass.

Step 9: Reinstall the socket

• Insert the socket back into the headlamp housing.
• Rotate clockwise by hand until it locks snugly.

Step 10: Reassemble what you removed

• If you pulled back the liner, reinstall all clips using the trim clip removal tool and flat trim tool to press them fully seated.
• If you removed an under-hood piece, reinstall bolts using the 10mm socket and 1/4" ratchet.
• If you removed the wheel, reinstall lug nuts with a 21mm socket, lower the truck, then Torque to 177 Nm (131 ft-lbs) with a torque wrench.

Step 11: Test operation

• Turn the ignition ON and test left and right turn signals and hazards.
• If the turn signal “fast flashes,” one bulb is still out (or the wrong bulb is installed).

✅ After Repair

• Confirm both front turn signals work normally (no rapid blinking).
• Walk around and verify the rear turn signal on that side also works (fast-flash can be caused by a rear bulb too).
• Recheck the fender liner is secured so it won’t rub the tire.
