🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm you’re on the correct bulb

• Use your flashlight and turn the hazard lights ON briefly to identify which front corner is out, then turn hazards OFF.
• The front turn signal bulb is typically the amber/turn + parking light bulb inside the headlamp housing.

Step 2: Access the rear of the headlamp housing

• Put on safety glasses and nitrile gloves.
• Use your flashlight to look behind the headlamp assembly from the engine bay.
• Find the socket that goes into the headlamp housing for the turn/park bulb (it will have a wiring connector attached).

Step 3: Remove the turn signal bulb socket

• Use your nitrile gloves for grip and rotate the bulb socket counterclockwise about 1/4 turn.
• Pull the socket straight out of the headlamp housing.
• If tight, wiggle gently—don’t force it.

Step 4: Remove the old bulb from the socket

• Use your shop towel to hold the bulb and pull it straight out of the socket.
• If it’s a wedge-style bulb, it’s a firm pull (no twisting).

Step 5: Install the new bulb

• Use nitrile gloves (or a shop towel) and push the new bulb straight into the socket until fully seated.
• Make sure it sits straight and evenly (crooked bulbs can cause intermittent operation).

Step 6: Reinstall the socket into the headlamp

• Insert the socket back into the headlamp opening.
• Use your nitrile gloves to rotate the socket clockwise about 1/4 turn until it locks.
• Give the socket a gentle tug to confirm it’s locked in place.

Step 7: Repeat on the other side (recommended)

• Use your flashlight and replace the bulb on the opposite headlamp the same way.
• Pairs age similarly; replacing both helps prevent another outage soon.

✅ After Repair

• 🧪 Turn the ignition to RUN and test: left signal, right signal, hazards, and parking lights.
• 🧪 Walk around the truck and confirm the flash rate is normal (a fast flash usually means a bulb is still out or not seated).
• 🧪 If the new bulb doesn’t light, remove it and re-seat the bulb and socket, then retest.
