⚠️ Safety & Precautions

• ⚠️ Turn lights OFF and let bulbs cool 10–15 minutes (they get very hot).
• ⚠️ Do not touch the new bulb’s glass—skin oil can shorten bulb life. Use gloves or hold the base.
• ⚠️ If you choose to disconnect the battery, remove the negative terminal first and keep it from springing back.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Identify which bulbs you’re replacing (low vs high)

• Use a flashlight to look behind the headlamp on each side.
• Low beam is the main nighttime beam; high beam is the brighter “brights” beam.
• Tip: Replace bulbs in pairs for matching color.

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

• If access is tight, use a trim clip removal tool to pop up any plastic push-clips holding a small air guide/cover near the headlamp (if equipped).
• If there’s a small bracket/cover with 10mm bolts in the way, remove them using a 10mm socket, 1/4" ratchet, and 6" extension, then set the parts aside.
• Tip: Lay clips/bolts in a cup so they don’t disappear.

Step 3: Remove the old bulb

• Reach behind the headlamp and press the lock tab on the wiring connector, then pull the connector straight off the bulb (use your fingers; no prying).
• Rotate the bulb base counterclockwise about 1/4 turn to unlock it, then pull the bulb straight out.
• Use a flashlight to confirm the bulb’s locating tabs and how it sits.

Step 4: Install the new bulb (don’t touch the glass)

• With nitrile gloves on, insert the new bulb into the headlamp the same way the old one came out (tabs must align).
• Rotate the bulb clockwise until it stops and feels fully locked. (No torque spec here—just turn until it seats firmly.)
• Push the wiring connector on until it clicks/locks.
• Tip: If you touched the glass, clean with alcohol.

Step 5: Repeat for the other bulb on the same side (if doing both)

• Repeat Steps 3–4 for the other headlight bulb (low or high beam) on that side.

Step 6: Repeat on the other headlamp (other side of the car)

• Move to the opposite side and repeat Steps 2–5.

Step 7: Reinstall any covers/clips you removed

• Reinstall any 10mm bolts you removed using a 10mm socket, 1/4" ratchet, and 6" extension (snug them—do not overtighten plastic mounts).
• Reinstall any push-clips by pressing them in by hand (use the trim clip removal tool only if needed to align the clip).

✅ After Repair

• 🔦 Turn on low beams, then high beams, and verify both sides work.
• 🧭 Check that the beams look even on a wall at night; if one seems “off,” the bulb may not be fully seated.
• 🧼 Wipe fingerprints off any surfaces you touched around the lamp area.
