🔧 Legacy - Headlight Bulb Replacement

You can replace the headlight bulbs from under the hood without removing the bumper. The main keys are using the correct bulb type and not touching the new bulb’s glass, which can shorten bulb life.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Identify which bulb you’re replacing (low vs high beam)

• Use a flashlight to look behind the headlight housing.
• Low beam is typically the larger rear access position; high beam is usually closer to the inner side of the housing.

Step 2: Create working room (only if your hands don’t fit)

• Use a flashlight to check if you can reach the bulb base comfortably.
• If a plastic clip or guide is in the way, use a small flathead screwdriver to gently release the clip (do not pry on the headlight lens).

Step 3: Remove the old bulb

• Put on nitrile gloves and safety glasses.
• Grip the bulb’s base (not the wiring) and rotate it counterclockwise about a quarter-turn to unlock it.
• Pull the bulb straight out of the headlight housing.

Step 4: Disconnect the electrical connector

• Press the connector lock tab and pull the connector straight off the bulb.
• If it’s stuck, use a small flathead screwdriver to gently help the lock tab move, then pull (do not break the tab).

Step 5: Install the new bulb (important handling rules)

• Keep nitrile gloves on and avoid touching the bulb glass.
• Plug the connector onto the new bulb until it clicks.
• Tip: A tiny dab helps prevent corrosion.
• If using it, apply a very small amount of dielectric grease to the connector seal area (not on the bulb glass).

Step 6: Lock the bulb into the headlight housing

• Insert the bulb straight into the opening, keeping it aligned with the housing’s tabs.
• Rotate clockwise about a quarter-turn until it stops (locked).

Step 7: Repeat on the other side

• Use the flashlight and repeat Steps 1-6 for the other headlight.
• Replace the left and right bulbs as a pair for even brightness and color.

✅ After Repair

• Turn the headlights ON and confirm both sides work on low beam.
• Switch to high beams and confirm both high beams work (if you replaced those too).
• Walk in front of your Legacy and verify both beams look even (no flicker, no dead bulb warning).
• If a bulb doesn’t light, turn lights OFF and re-check the connector is fully clicked in and the bulb is fully locked.
