⚠️ Safety & Precautions

• Turn the headlights off and let the bulbs cool before starting.
• Do not touch the glass on halogen bulbs. Skin oils can shorten bulb life.
• If your RAV4 has HID or LED headlamp units, the bulb area may have high-voltage components. Do not open any ballast or driver housing.
• Use care around the front bumper and headlamp lens. Scratches are easy to make.
• Battery disconnect is not required for a basic bulb swap, but the lights should be switched off.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open access to the headlamp area

• Open the hood and locate the rear of each headlamp housing.
• If space is tight, use the 10mm socket, ratchet, and short extension to remove any nearby intake duct or cover that blocks access.
• Keep removed fasteners organized.

Step 2: Remove the bulb cover

• Use your hand to twist off the rear dust cap or bulb cover on one side.
• If the cover is stuck, gently use a flat-blade trim tool to start it loose.
• Do not force plastic parts.

Step 3: Disconnect the bulb

• Wear latex or nitrile gloves before handling the new bulb.
• Press the connector tab and pull the electrical connector straight off the bulb.
• If there is a retaining ring or clip, release it carefully by hand.

Step 4: Remove the old bulb

• Use your hand to twist the bulb counterclockwise and pull it straight out.
• Keep the bulb upright so you can compare the indexing tabs on the new bulb.
• Do not touch the glass.

Step 5: Install the new bulb

• Line up the new bulb with the tabs and insert it into the housing.
• Twist it clockwise by hand until fully seated.
• Reconnect the electrical connector until it clicks into place.
• There is no torque spec for the bulb itself; it should be snug and fully locked by hand.

Step 6: Reinstall the cover and repeat on the other side

• Reinstall the dust cap or bulb cover by hand until it seals fully.
• Put back any air duct or cover you removed using the 10mm socket and ratchet.
• Repeat the same process on the other headlight bulb.
