• 🧼 Do not touch the new bulb’s glass with bare fingers; skin oils can shorten bulb life.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm the correct bulb is out

• Turn the hazard lights ON briefly, walk around, and confirm which front signal is not blinking.
• Turn hazards OFF and ignition OFF before you start work.

Step 2: Access the rear of the headlamp (engine-bay method)

• Use a flashlight to find the turn signal bulb socket on the back of the headlamp (usually the outboard/lower area of the housing).
• If access is tight, remove any small plastic air guide/cover near the headlamp by releasing clips with a trim clip removal tool and/or removing bolts with a 10mm socket, 3/8" ratchet, and 6" socket extension.
• Set clips/bolts aside in a small pile so nothing is lost.

Step 3: Alternate access (wheel-well method if the back is blocked)

• Turn the front wheel away from the side you’re working on (this creates room).
• Use a Phillips #2 screwdriver and trim clip removal tool to loosen the front section of the inner fender liner (you only need enough space to reach the back of the headlamp).
• Use a flashlight to locate the turn signal socket from behind the liner.

Step 4: Remove the turn signal bulb socket

• Put on nitrile gloves and safety glasses.
• Press the electrical connector tab and pull the connector straight off the socket by hand.
• Grab the socket and twist it about 1/4 turn counterclockwise, then pull it straight out of the headlamp.
• If stuck, wiggle gently—don’t force it.

Step 5: Replace the bulb

• Remove the old bulb from the socket (most pull straight out; some require a gentle twist and pull).
• Install the new front turn signal bulb (amber) into the socket firmly.
• If the socket seal (O-ring) is damaged, replace it with a new bulb socket O-ring seal.
• Don’t touch bulb glass—use gloves.

Step 6: Reinstall the socket

• Insert the socket back into the headlamp housing, making sure it sits flush.
• Twist clockwise about 1/4 turn until it locks.
• Reconnect the electrical connector until it clicks.

Step 7: Reassemble any covers or liner

• If you removed engine-bay covers, reinstall them using the 10mm socket, 3/8" ratchet, and 6" socket extension.
• If you loosened the fender liner, reinstall screws/clips using a Phillips #2 screwdriver and trim clip removal tool.

✅ After Repair

• Turn hazards ON and verify both front turn signals flash at a normal speed.
• Test left and right turn signals from the stalk.
• If a signal flashes fast, recheck the bulb is fully seated and the connector clicked in.
