⚠️ Safety & Precautions

• ⚠️ Turn lights off and let bulbs cool; they get extremely hot.
• ⚠️ Wear gloves—skin oils on the bulb glass can shorten bulb life.
• ⚠️ Do not touch the new bulb’s glass; hold it by the base.
• ⚠️ If you choose to disconnect the battery, use a 10mm wrench and keep the key out of the ignition.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the hood and identify the bulbs

• Use a flashlight to look behind each headlight assembly.
• The low beam (9006) and high beam (9005) are the round twist-lock bulb sockets at the back of the headlight.

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

• If something is blocking your hand, loosen/remove the nearby plastic ducting or covers using an 8mm socket with a 1/4" ratchet and/or a flat-blade screwdriver.
• If you encounter plastic push-clips, remove them with a trim clip removal tool (it slides under the clip head to pop it up).

Step 3: Remove the first bulb (driver or passenger side)

• Reach behind the headlight and grasp the bulb’s plastic base.
• Twist the bulb base counterclockwise (about a quarter turn) by hand to unlock it.
• Pull the bulb straight out of the headlight housing.

Step 4: Disconnect the electrical connector

• Press the connector lock tab and pull the connector off the bulb base.
• If it’s stuck, use a flat-blade screwdriver gently to help depress the tab—don’t pry on the wires.

Step 5: Install the new bulb

• Put on nitrile gloves (prevents oil on the glass).
• Plug the electrical connector onto the new bulb until it clicks.
• Align the bulb’s tabs with the headlight housing slots, insert the bulb fully, then twist clockwise to lock.
• Tip: If it won’t lock, it’s not seated.

Step 6: Repeat on the other side

• Repeat Steps 3–5 for the other headlight.
• If you’re replacing high beams too, repeat the same process on the high beam bulb socket (use the flashlight to confirm you’re on the correct bulb).

Step 7: Reinstall anything you removed

• Reinstall ducts/covers and tighten fasteners using an 8mm socket and 1/4" ratchet.
• If you disconnected the battery, reconnect the negative terminal using a 10mm wrench.

✅ After Repair
