🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the rear of the headlamp

• Open the hood and locate the back of each headlight assembly.
• If access is blocked, use the trim panel removal tool (specialty) and 7mm socket to remove the small upper air deflector or cover pieces near the headlamp.
• Keep the fasteners organized.

Step 2: Remove the old bulb

• Reach behind the headlight and disconnect the bulb electrical connector by hand.
• Turn the bulb socket counterclockwise with your hand, or use a 7mm socket if a retaining screw or cover is present on your lamp style.
• Pull the bulb straight out once released.

Step 3: Install the new bulb

• Put on gloves before handling the new bulb.
• Insert the new bulb into the housing in the same position as the old one.
• Lock the bulb in place by turning it clockwise until secure.
• Reconnect the electrical connector firmly.
• Torque to snug only; do not overtighten plastic bulb retainers.

Step 4: Repeat on the other side

• Do the same procedure on the opposite headlamp.
• Replace both bulbs as a pair so the light output matches.

Step 5: Reinstall covers and test

• Reinstall any removed covers or air deflectors using the 7mm socket and trim panel removal tool (specialty).
• Turn the headlights on and verify low beam and high beam operation.
• Check the beam pattern against a wall before driving at night.

✅ After Repair
