⚠️ Safety & Precautions

• ⚠️ Turn the headlight switch OFF and remove the key before starting.
• ⚠️ Let bulbs cool first; they get extremely hot.
• ⚠️ Do not touch the new bulb’s glass with bare fingers; skin oil can shorten bulb life. Use clean gloves.
• ⚠️ If you must lift the car battery cover area or move intake parts, keep tools away from the battery terminals.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Identify which bulb you’re replacing

• Use a flashlight to look behind the headlamp assembly (from the engine bay).
• On your Impala there are typically two bulbs per side: low beam (9006) and high beam (9005).
• Replace bulbs in pairs for matching color.

Step 2: Remove the electrical connector

• Put on nitrile gloves and safety glasses.
• Reach behind the headlamp and locate the connector on the back of the bulb.
• Press the connector lock tab (use a small flat-blade screwdriver only if needed) and pull the connector straight off.
• Wiggle gently—don’t yank the wires.

Step 3: Remove the bulb from the housing

• Grip the bulb base and rotate it counterclockwise about a quarter-turn to unlock.
• Pull the bulb straight out.

Step 4: Install the new bulb

• Open the new bulb package and handle the bulb by the plastic base (use nitrile gloves).
• Align the bulb tabs with the housing slots and insert the bulb fully.
• Rotate clockwise about a quarter-turn until it locks.
• If you accidentally touch the glass, wipe it clean with a lint-free cloth (use the nitrile gloves to avoid re-contaminating).

Step 5: Reconnect the electrical connector

• Push the connector onto the bulb until it clicks/locks.
• Gently tug to confirm it’s secure.

Step 6: Repeat on the other headlight

• Repeat Steps 2–5 for the bulb on the opposite side.
• If passenger-side access is tight, you may need to loosen/remove an air intake duct fastener using a 10mm socket, 3/8" ratchet, and 3" extension, then reinstall it afterward.
