🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the headlamp access area

• Open the hood and locate the back of the headlamp assembly on the side you are servicing.
• Find the round or rectangular access cover behind the lamp.
• If needed, use a trim removal tool to gently release the cover without cracking it.

Step 2: Remove the bulb holder

• Turn the turn signal bulb holder counterclockwise by hand to unlock it.
• Pull the holder straight out of the headlamp housing.
• Keep the bulb pointed up to avoid dropping it.

Step 3: Replace the bulb

• Remove the old bulb from the holder by pulling it straight out.
• Install the new front turn signal bulb into the holder fully.
• Do not force it. The bulb should seat cleanly.

Step 4: Reinstall the bulb holder

• Insert the bulb holder back into the headlamp housing.
• Turn it clockwise by hand until it locks in place.
• Reinstall the access cover and make sure it seals tightly.

Step 5: Test the new bulb

• Turn the ignition on and activate the turn signal.
• Check that the new bulb flashes normally.
• Repeat the same procedure on the other side if needed.

✅ After Repair
