⚠️ Safety & Precautions

• ⚠️ Turn the lights off and let bulbs cool for 10+ minutes (they get very hot).
• ⚠️ Do not touch the glass on halogen bulbs; skin oil can shorten bulb life. Use clean gloves.
• ⚠️ Support the headlamp assembly so it doesn’t scratch the bumper or fender.
• Battery disconnect is not required for this job.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the headlamp locking pins

• Locate the two vertical locking pins at the top of the headlamp assembly (right behind the grille).
• If they’re tight, use a small flathead screwdriver to gently pry upward, then pull them out by hand.
• If needed, use needle-nose pliers to pull the pins straight up. (Needle-nose pliers are slim pliers for grabbing small parts.)

Step 2: Pull the headlamp assembly forward

• Use both hands to slide the headlamp assembly straight forward.
• Place a clean shop towel on the bumper edge to prevent scratches, and rest the assembly gently against it.
• Don’t force it; it slides straight out.

Step 3: Remove the old bulb(s)

• From behind the headlamp, identify the bulb you’re replacing:
• Low beam is typically the H11 bulb; high beam is typically the 9005 bulb.
• Use your flashlight to see the socket tabs clearly.
• Twist the bulb socket counterclockwise by hand to unlock it, then pull it straight out.
• Press the electrical connector tab and unplug the bulb. If it’s stubborn, use a small flathead screwdriver to gently help lift the tab.

Step 4: Install the new bulb(s)

• With nitrile gloves on, plug the new bulb into the connector until it clicks.
• Insert the bulb into the headlamp housing, making sure it sits flush.
• Twist clockwise by hand to lock it in place.
• If you accidentally touch the glass, wipe it with the clean shop towel before installing.

Step 5: Reinstall the headlamp assembly

• Guide the headlamp assembly back into position, aligning the tabs/pegs.
• Reinstall the two locking pins by pushing them straight down by hand until fully seated.

Step 6: Repeat on the other side

• Repeat Steps 1–5 for the other headlamp assembly so both sides match in brightness and color.
• Replacing bulbs in pairs helps even lighting.

✅ After Repair
