🔧 CX-5 - Headlight Bulb Replacement

To replace “both headlight bulbs,” we need to access each headlamp from inside the engine bay (usually behind the headlight housing). The exact bulb type and steps change depending on whether you’re replacing the low beams, high beams, or another bulb inside the headlight.

Difficulty Level: Beginner | Estimated Time: 0.5-1.5 hours


⚠️ Safety & Precautions

  • ⚠️ Turn the lights OFF and let bulbs cool before touching.
  • ⚠️ Do not touch the glass of a halogen bulb with bare fingers (skin oil shortens bulb life).
  • ⚠️ Support the hood securely; keep loose clothing away from moving parts.
  • ⚠️ Battery disconnect is not usually required, but keep the headlight switch OFF while working.

🔧 Required Tools

You'll need the following tools for this repair:

  • Nitrile gloves
  • Safety glasses
  • Flashlight
  • Trim clip removal tool
  • Flathead screwdriver
  • 10mm socket
  • 1/4" ratchet
  • 6" extension

🔨 Step-by-Step Instructions

Follow these steps in order:

Before I continue: Which bulbs are you replacing on your CX-5?

  • Low beam bulbs (the main headlights), or high beam bulbs?
  • Also—are your headlights halogen with replaceable bulbs, or LED (often the whole headlamp is not a simple bulb swap)?

Reply “low beam halogen” or “high beam halogen”, etc.


✅ After Repair

  • Turn headlights ON and confirm both sides work.
  • Verify the beam pattern looks even left-to-right.
  • If one side doesn’t light, turn OFF and re-check the connector is fully seated.
