• ⚠️ Let the bulbs cool first; they can be hot.
• ⚠️ Don’t touch the new bulb glass with bare fingers (skin oils shorten bulb life). Use gloves or a clean paper towel.
• ⚠️ Support the headlamp assembly so it doesn’t scratch the bumper or fender.
• ⚠️ Battery disconnect is not required for this repair.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open access to the headlamp area

• Open the hood and locate the headlamp assembly behind the lens.
• Use a flashlight to identify the headlamp retaining hardware at the top of the assembly.

Step 2: Remove the headlamp retaining pins/fasteners

• Use a flat trim tool or flathead screwdriver (medium) to lift and remove the headlamp retaining pins (or release their locks, depending on what you see).
• If your side has a small bolt instead of (or in addition to) a pin, remove it using a 10mm socket, 1/4" ratchet, and 6" socket extension (1/4").
• Keep the pins/bolts together per side.

Step 3: Slide the headlamp assembly forward

• Grip the headlamp housing and pull it straight forward gently.
• If it feels stuck, wiggle slightly while pulling—don’t pry against the painted bumper.

Step 4: Remove the turn signal bulb socket

• Find the turn signal/park bulb socket on the back of the headlamp (it’s one of the smaller twist-lock sockets).
• Twist the socket counterclockwise by hand to unlock it, then pull it straight out.

Step 5: Replace the bulb

• Pull the old bulb straight out of the socket.
• Install the new bulb by pushing it straight into the socket until fully seated.
• Use nitrile gloves to avoid touching the glass.

Step 6: Reinstall the socket and headlamp

• Reinsert the socket into the headlamp and twist clockwise until it locks.
• Slide the headlamp assembly back into position, lining up the locating tabs.
• Reinstall the retaining pins and/or bolts:
  • If bolts were removed, tighten with a 10mm socket and 1/4" ratchet until snug (do not overtighten).

Step 7: Repeat on the other side

• Repeat Steps 2–6 for the opposite headlamp.

✅ After Repair

• Turn the ignition to ON and test:
  • Left and right turn signals
  • Hazard lights
  • Parking lights (the bulb is often dual-function)
• If the turn signal blinks fast, the bulb may be the wrong type, not seated fully, or there may be another bulb out.
• Make sure the headlamp sits evenly and the pins/bolts are fully installed.
