⚠️ Safety & Precautions

• ⚠️ Let headlights cool first—bulbs get extremely hot.
• ⚠️ Don’t touch the new bulb’s glass with bare fingers (skin oil can shorten bulb life). Use clean gloves.
• ⚠️ Turn the headlight switch OFF and remove the key before unplugging anything.
• ⚠️ Battery disconnect is not required for this repair.

📋 Before You Begin

• Park on level ground, shift to Park, and set the parking brake.
• Open the hood and support it securely.
• Decide which headlights you have:
  • If there’s a removable bulb connector going into the back of the headlamp: you have replaceable halogen bulbs.
  • If the back looks like a sealed module with no bulb you can twist out: you likely have an LED headlamp assembly (the “bulb” isn’t separately serviceable).

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm headlight type

• Use a flashlight to look behind each headlamp for a round bulb base you can twist out.
• If you do NOT see a twist-out bulb base, stop here and tell me if your headlamps are LED—those require headlamp assembly service, not bulb replacement.

Step 2: Make room (only if your hand won’t fit)

• If the passenger side is tight near the air intake, use an 8mm socket with a 1/4" drive ratchet to loosen the intake clamp(s) just enough to move the tube/box slightly.
• If a plastic push-clip is in your way, use a flat trim tool to pop it up carefully.
• More space prevents broken connectors.

Step 3: Unplug the headlight bulb connector

• Put on nitrile gloves and safety glasses.
• At the back of the headlamp, grasp the electrical connector and pull it straight off the bulb base.
• If it’s stubborn, wiggle gently—don’t yank on the wires.

Step 4: Remove the old bulb

• Hold the bulb base and rotate it counterclockwise to unlock it (about a quarter turn), then pull it straight out.
• Note the orientation tabs so the new bulb goes in the same way.

Step 5: Install the new bulb

• With nitrile gloves on, insert the new H13/9008 headlight bulb into the housing, aligning the tabs.
• Rotate the bulb clockwise until it locks in place.
• If you accidentally touch the glass, wipe it clean with rubbing alcohol (use a clean lint-free cloth).

Step 6: Reconnect the connector

• Push the electrical connector back onto the bulb until fully seated.

Step 7: Repeat on the other side

• Use the same steps for the other headlight.
• If you loosened any intake parts, reinstall them and tighten with the 8mm socket and 1/4" drive ratchet (snug, do not overtighten).

✅ After Repair

• Turn the headlights ON and confirm low beams work on both sides.
• Switch to high beams and confirm both sides change brightness (on halogen H13, high/low are in the same bulb).
• If one side doesn’t work, turn lights OFF and re-check the connector is fully seated and the bulb is locked.
