🔧 CX-5 - Headlight Bulb Replacement

On your CX-5, the “headlight bulbs” can mean the low beams and/or the high beams. Both are accessible from the engine bay without removing the headlight assembly, and replacing them in pairs keeps the light color and brightness matched.

Difficulty Level: Beginner | Estimated Time: 0.5-1.0 hours

⚠️ Safety & Precautions

• ⚠️ Turn the light switch OFF and remove the key before starting.
• ⚠️ Let the bulbs cool 10+ minutes; halogen bulbs get extremely hot.
• ⚠️ Do not touch the new bulb glass with bare fingers; skin oil shortens bulb life. Use clean gloves.
• ⚠️ If you accidentally touch the glass, clean it with isopropyl alcohol and a lint-free towel.
• ⚠️ Battery disconnect is not required, but keep metal tools away from the battery positive terminal.

📋 Before You Begin

• Park on level ground, set the parking brake, and open the hood.
• Turn the headlight switch to OFF and remove the key.
• Set your flashlight so it shines behind the headlight area you’re working on.
• Work one bulb at a time to avoid mix-ups.

🔨 Step-by-Step Instructions

Follow these steps in order:

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

• Use your flashlight and look behind the headlight housing from the engine bay.
• The headlight has two main rear bulb locations: one for low beam (H11) and one for high beam (9005).
• If unsure: low beam is the one used most.

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

• If access is tight, remove nearby plastic clips using a trim clip removal tool.
• If a clip is stubborn, gently assist with a small flathead screwdriver (do not pry hard).
• If a small bracket/cover uses bolts, remove with a 10mm socket, 1/4" ratchet, and 6" extension.

Step 3: Disconnect the bulb electrical connector

• Put on nitrile gloves and safety glasses.
• Press the connector locking tab by hand; if needed, gently assist with a small flathead screwdriver.
• Pull the connector straight off the bulb (don’t pull on the wires).

Step 4: Remove the old bulb

• Grip the bulb base and rotate it counterclockwise by hand to unlock.
• Pull the bulb straight out of the headlight housing.
• Use your flashlight to check the opening for dirt or moisture.

Step 5: Install the new bulb (no touching the glass)

• Handle the new bulb only by the base while wearing nitrile gloves.
• If the bulb glass is touched, clean it using isopropyl alcohol (70%+) and lint-free shop towels, then let it dry.
• Insert the bulb into the housing, lining up the tabs, then rotate clockwise until it locks fully.
• If it won’t lock, don’t force—re-align tabs.

Step 6: Reconnect the electrical connector

• Push the connector onto the bulb until the tab clicks into place.
• Gently tug on the connector to confirm it’s locked.

Step 7: Repeat on the other side

• Replace the matching bulb on the other headlight using the same steps.
• Replace in pairs for even brightness.

Step 8: Reinstall any clips/bolts you removed (if applicable)

• Reinstall plastic clips by hand; use the trim clip removal tool only to align them.
• Reinstall any 10mm bolts using the 10mm socket, 1/4" ratchet, and 6" extension (snug only; these are small fasteners).

✅ After Repair

• Switch to high beams to confirm both work (if you replaced highs).
• Walk in front of the car and verify left/right brightness and color match.
• If a bulb doesn’t light, turn lights off and re-check the connector is fully seated.
