🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm the correct bulb location

• Turn the hazard lights ON briefly to see which front lamp is flashing, then turn them OFF.
• Use a flashlight to look behind that headlamp; you’re looking for the turn-signal socket going into the back of the headlamp housing.

Step 2: Create working room (only if access is tight)

• If your hands don’t fit, remove nearby items for space.
• Use a 10mm socket with a 3/8" ratchet and 6" extension to loosen/remove any small brackets or covers that block access.
• If you encounter plastic push-clips, pop them out using a trim clip removal tool (it’s a forked tool that lifts clips without breaking them).

Step 3: Remove the turn signal bulb socket

• Put on nitrile gloves and safety glasses.
• Grab the turn-signal socket at the back of the headlamp.
• Twist the socket counterclockwise about 1/4 turn by hand, then pull it straight out.

Step 4: Remove the old bulb

• Pull the bulb straight out of the socket (no twisting on most versions).
• Compare the old bulb to the new one to confirm the base style matches.

Step 5: Install the new bulb

• Push the new bulb straight into the socket until fully seated.
• Tip: Don’t touch the glass portion.

Step 6: Reinstall the socket

• Insert the socket back into the headlamp housing.
• Twist clockwise about 1/4 turn until it locks snugly by hand (do not over-tighten).

Step 7: Reassemble any parts you moved

• Reinstall any brackets/covers you removed using the 10mm socket, 3/8" ratchet, and 6" extension.
• Reinstall plastic clips by pushing them back in by hand; use the trim clip removal tool only if you need to align the clip hole.

Step 8: Repeat on the other side

• Replace the other front turn signal bulb the same way.
• Tip: Replacing in pairs keeps brightness even.

✅ After Repair

• Turn ignition ON and test: left turn, right turn, and hazards.
• Verify the turn signal flashes normally (not fast). Fast flashing usually means a bulb isn’t working or isn’t seated.
• Walk around the truck to confirm front and rear signals work on both sides.
