• ⚠️ Let the headlamp area cool if lights were on (bulbs get hot).
• ⚠️ Don’t touch the new bulb glass with bare fingers; skin oil can shorten bulb life.
• ⚠️ If you must raise the vehicle for access (usually not needed), support it with jack stands.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm the correct bulb socket

• Use a flashlight to look behind the headlamp on the side you’re replacing.
• Find the socket that lines up with the amber turn signal area of the headlamp lens.
• If unsure, activate hazards briefly, then OFF.

Step 2: Remove the turn signal bulb socket

• Reach behind the headlamp and grasp the socket body firmly.
• Twist the socket counterclockwise about 1/4 turn, then pull it straight out.
• If it’s tight, use a small flathead screwdriver gently to help you start the twist (do not pry on the plastic lens).

Step 3: Remove the old bulb from the socket

• Pull the bulb straight out of the socket (it’s a push-in style on most builds).
• Use a paper towel to grip it if it’s stuck.

Step 4: Install the new bulb

• Hold the new bulb with nitrile gloves or a clean paper towel.
• Push the bulb straight into the socket until fully seated.

Step 5: Reinstall the socket into the headlamp

• Line up the socket tabs with the headlamp housing.
• Push the socket in, then twist clockwise about 1/4 turn until it locks.
• It should feel snug, not forced.

Step 6: Repeat on the other side

• Replace the bulb on the opposite headlamp using the same steps.
• Replacing in pairs keeps brightness and color even.

✅ After Repair

• ✅ Turn the ignition ON and test left and right turn signals.
• ✅ Turn on the hazard lights and confirm both front signals flash evenly.
• ✅ Walk around and verify no “fast flash” on the dash (fast flash usually means a bulb isn’t working or isn’t seated).
