⚠️ Safety & Precautions

• ⚠️ Turn the headlights off and let bulbs cool for 10-15 minutes before touching anything.
• ⚠️ Do not touch the glass part of a new bulb with bare fingers; skin oil can shorten bulb life.
• ⚠️ If equipped with HID (xenon), the system can carry high voltage; do not unplug the ballast with the lights on.

🔨 Step-by-Step Instructions

Follow these steps in order:

Quick check (needed before steps): Identify your headlight type

• Look at the headlight lens: a “projector” lens with a blue/white tint and “D” style bulb usually indicates HID; a more standard reflector style usually indicates halogen.
• If you’re not sure: tell me if your headlights say “D3S” or “H11/9005” on the bulb/box, or send a quick photo of the back of the headlight housing.

Step 1: Access the bulb (rear of headlamp)

• Use a flashlight to locate the round dust cap or bulb socket at the back of the headlight assembly (driver and passenger sides).
• If a plastic cover/air guide is in the way, use a trim clip removal tool or small flathead screwdriver to pop the push-clips up (work gently so the clips don’t break).

Step 2: Remove the dust cap (if equipped)

• Use your hand to twist the cap counterclockwise and pull it off.
• Set the cap where it won’t collect dirt.

Step 3A (Halogen): Remove the old bulb

• Put on nitrile gloves.
• Unplug the electrical connector by pressing the lock tab with your thumb (use a small flathead screwdriver only if the tab is stubborn).
• Twist the bulb counterclockwise (about 1/4 turn) and pull it straight out.

Step 3B (HID/Xenon): Remove the old bulb

• Put on nitrile gloves and safety glasses.
• Make sure the lights have been OFF for several minutes.
• Carefully disconnect the igniter/connector from the bulb (release the lock; use a small flathead screwdriver gently if needed).
• Rotate the bulb retaining ring (or bulb base) counterclockwise and remove the bulb straight out.

Step 4: Install the new bulb

• Keep nitrile gloves on and avoid touching the bulb glass.
• Align the bulb tabs with the housing slots, insert fully, then twist clockwise to lock.
• Reconnect the electrical connector until it clicks.

Step 5: Reassemble

• Reinstall the dust cap (twist clockwise to lock).
• Reinstall any covers/air guides and push-clips using a trim clip removal tool (or by hand).

Step 6: Repeat on the other side

• Repeat Steps 1-5 for the other headlight.
• Replace bulbs in pairs for matching color/brightness.

✅ After Repair

• Turn the headlights ON and verify both sides work on low beam and high beam.
• If a bulb doesn’t light: turn lights OFF, re-check the connector is fully seated, and confirm the bulb is locked in place.
• Check aim at night on a flat wall; if the pattern looks uneven, tell me and I’ll walk you through aiming.
