🔧 Soul - Headlight Bulb Replacement

Replacing the headlight bulbs is usually done from behind each headlight housing in the engine bay. The main “gotcha” is using the correct bulb type and not touching the new bulb’s glass with your fingers (oil shortens bulb life).

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


⚠️ Safety & Precautions

  • 🧤 Turn headlights OFF and let bulbs cool (they get very hot).
  • 👓 Wear safety glasses and gloves; bulbs can shatter if dropped.
  • 🖐️ Do not touch the bulb glass; hold the base only. If touched, clean with isopropyl alcohol and a lint-free cloth.
  • 🔋 If you need more room on the driver side, disconnect the negative battery cable first.

🔧 Required Tools

You'll need the following tools for this repair:

  • Safety glasses
  • Nitrile gloves
  • Flashlight
  • 10mm socket
  • 1/4" ratchet
  • 6" socket extension
  • Phillips screwdriver
  • Trim clip removal tool
  • Torque wrench (in-lb)

🔩 Required Parts

HowToo sells all the parts you need for this repair:

  • Headlight bulb (match your bulb type) - Qty: 2
  • Dielectric grease (for bulb connector) - Qty: 1

📋 Before You Begin

  • 🚗 Park on level ground, shift to Park, and turn the ignition OFF.
  • 🔦 Identify your bulb setup first: look behind the headlight for the bulb base label (common setups are a single bulb for both low/high, or separate low-beam and high-beam bulbs).
  • 🔋 If access is tight on the driver side, plan to disconnect the negative battery cable using a 10mm socket.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm the correct bulb type (quick check)

  • Open the hood and use a flashlight to look behind the headlight.
  • Look for a label on the bulb base or housing, or count connectors:
  • If there is one main bulb connector, you likely have a single bulb that does both low/high.
  • If there are two separate bulb connectors, you have separate low-beam and high-beam bulbs.
  • Match bulbs exactly to the label.

Step 2: Make room for your hands (only if needed)

  • If something blocks access (intake snorkel/cover), remove fasteners using a Phillips screwdriver and/or trim clip removal tool.
  • If you need extra room on the driver side, disconnect the battery negative terminal using a 10mm socket and 1/4" ratchet.
  • When reinstalling the battery terminal later: Torque to 5 Nm (44 in-lbs).

Step 3: Remove the old bulb

  • Reach behind the headlight and pull the electrical connector straight off the bulb (wiggle gently by hand with nitrile gloves on).
  • If there is a rear dust cap, rotate it counterclockwise by hand and remove it.
  • Remove the bulb:
  • If it’s a twist-lock bulb, rotate the bulb counterclockwise and pull it out.
  • If it uses a wire retainer clip, press/unhook the clip and swing it away, then pull the bulb out.

Step 4: Install the new bulb (no glass touching)

  • Put on nitrile gloves and only hold the new bulb by the base.
  • Install the new bulb in the same orientation as the old one:
  • For twist-lock: insert fully, then rotate clockwise until it stops snugly.
  • For retainer clip: seat the bulb fully, then latch the clip back in place.
  • Apply a tiny amount of dielectric grease to the inside of the electrical connector (optional but helpful), then push the connector on until fully seated.
  • Reinstall the dust cap (if equipped) by hand, turning clockwise until snug.

Step 5: Repeat on the other side

  • Do the same removal/installation steps on the opposite headlight.
  • Replace bulbs in pairs for even brightness.

Step 6: Reassemble and test

  • Reinstall any intake snorkel/covers using a Phillips screwdriver and/or trim clip removal tool.
  • If disconnected, reconnect the battery negative terminal using a 10mm socket and torque wrench (in-lb): Torque to 5 Nm (44 in-lbs).
  • Turn headlights ON and confirm low-beam and high-beam operation.

✅ After Repair

  • 🔎 Check both low beams and high beams, plus turn signals/parking lights (easy to bump a connector).
  • 🧽 If one side looks dim or scattered, the bulb may not be fully seated—turn off lights, cool down, and reseat it.
  • 🛣️ At night, verify beam aim looks normal (not pointing too high or too low).

💰 DIY vs Shop Cost

Shop Cost: $120-$250 (parts + labor)

Quick question (so I match the bulbs perfectly): Do you have a single headlight bulb that does both low/high, or separate low-beam and high-beam bulbs? If you can, tell me what’s printed on the old bulb (example formats: H13, H11, 9005, etc.).
