⚠️ Safety & Precautions

• ⚠️ Turn headlights OFF and let bulbs cool 10+ minutes; they get extremely hot.
• ⚠️ Do not touch halogen bulb glass with bare fingers; skin oil can shorten bulb life.
• ⚠️ Support the hood securely and keep tools/clothing clear of the cooling fan area.
• ⚠️ Battery disconnect is not required, but keep the headlight switch OFF during the work.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the back of the headlamp

• Open the hood and stand behind the headlight you’re replacing.
• Use a flashlight to locate the round bulb base and wiring connector behind the headlamp.

Step 2: Unplug the headlight connector

• Grip the connector at the back of the bulb (not the wires).
• Pull the connector straight off the bulb. If it’s stubborn, wiggle gently while pulling.
• If you have it, apply a tiny amount of dielectric grease to the connector seal for easier future removal.

Step 3: Remove the old bulb

• Hold the bulb base firmly and rotate it counterclockwise about a quarter-turn to unlock.
• Pull the bulb straight out of the headlamp housing.
• Use a clean shop towel to handle the bulb if you’re not wearing gloves.

Step 4: Install the new bulb

• Compare the new bulb to the old one to confirm the same style and locking tabs.
• Insert the new bulb into the housing, lining up the tabs with the slots.
• Rotate the bulb clockwise until it locks fully. It should seat flat, no wobble.
• If you accidentally touch the glass, wipe it with the clean shop towel before installing.

Step 5: Reconnect and test

• Push the connector back onto the bulb until it’s fully seated.
• Turn headlights ON and confirm the low beam works.
• Switch to high beams and confirm operation.

Step 6: Repeat on the other side

• Repeat Steps 1-5 for the other headlight so brightness and color match. New + old bulbs won’t match well.

✅ After Repair

• Verify low beam and high beam operation on both sides.
• At night, confirm the beams look even and the road is evenly lit.
• If a bulb doesn’t light, turn lights OFF and re-check the connector seating.
