⚠️ Safety & Precautions

• ⚠️ Turn ignition OFF and remove the key before starting.
• ⚠️ Let the headlight area cool first; bulbs and housings can get hot.
• ⚠️ Don’t touch the bulb glass with bare fingers; skin oils can shorten bulb life.
• ⚠️ If you must unplug any electrical connector, pull on the connector body, not the wires.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Verify the correct side

• Turn the hazard lights ON briefly to confirm which front bulb is out, then turn the hazards OFF.
• Use safety glasses and a flashlight so you can see behind the headlight housing.

Step 2: Access the turn signal bulb socket

• From the engine bay, look behind the headlight assembly on the side you’re replacing.
• Find the turn signal bulb socket (it will be an electrical socket that twists into the headlight housing).
• Use a flashlight to confirm you’re on the turn signal socket and not the low/high beam.

Step 3: Remove the bulb socket

• Grip the socket and rotate it counterclockwise about 1/4 turn, then pull it straight out.
• If it’s tight, use a small flat trim tool gently to help you start the twist. Don’t pry on the plastic hard.

Step 4: Remove the old bulb

• Put on nitrile gloves.
• Pull the old bulb straight out of the socket (it’s a push-in style on most Optima setups).
• If your bulb is a twist-lock style, rotate it slightly while pulling until it releases.

Step 5: Install the new bulb

• With nitrile gloves on, push the new bulb fully into the socket until it seats.
• Make sure it sits straight and doesn’t wobble.

Step 6: Reinstall the socket

• Insert the socket back into the headlight housing, lining up the tabs.
• Rotate clockwise about 1/4 turn until it locks in place.

Step 7: Function test

• Turn the ignition to ON and switch on the left/right turn signal for the side you replaced.
• Confirm normal flash speed and that the bulb lights up amber.
• If it doesn’t light, turn ignition OFF and re-seat the bulb and socket, then test again.

✅ After Repair

• Check both front turn signals and hazards to confirm consistent brightness and normal blink rate.
• If one side still blinks fast, replace the bulb on the other side too (bulbs often fail close together).
