🔧 Seltos - Front Turn Signal Bulb Replacement

Your Seltos front turn signals use a removable bulb/socket (on halogen-equipped headlights). You’ll access the back of the headlamp from inside the front wheel-well area, swap the bulb, then confirm the blink rate is normal.

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


⚠️ Safety & Precautions

  • ⚠️ Turn the ignition OFF and switch all lights OFF before starting.
  • ⚠️ Let the headlamp area cool if lights were on (hot bulb/housing).
  • ⚠️ Don’t touch the new bulb glass with bare fingers (oil can shorten bulb life); use gloves.
  • ⚠️ If your Seltos has LED front turn signals, there may be no replaceable “bulb” (the lamp/module or headlamp assembly is serviced instead).

🔧 Required Tools

You'll need the following tools for this repair:

  • Nitrile gloves
  • Safety glasses
  • Trim clip removal tool
  • Phillips screwdriver #2
  • 10mm socket
  • 1/4" ratchet
  • Flashlight

🔩 Required Parts

HowToo sells all the parts you need for this repair:

  • Front turn signal bulb (amber) - Replace in pairs - Qty: 2
  • Replacement plastic push-clips (fender liner) - Qty: 2-6

📋 Before You Begin

  • Park on level ground, shift to Park, and set the parking brake.
  • Turn the steering wheel fully away from the side you’re working on (gives more hand room in the wheel well).
  • Have your new bulb ready, but don’t open the package until you’re ready to install it.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm you have a replaceable bulb

  • Use a flashlight and look behind the headlamp through the wheel-well access area.
  • If you see a round twist-lock socket with wires going to it, you have a serviceable bulb.
  • If you do not see a bulb socket and the turn signal appears to be an LED strip/module, stop here (it may not be a bulb replacement).

Step 2: Open the wheel-well access

  • Wear safety glasses and nitrile gloves.
  • Use a trim clip removal tool to remove the plastic push-clips holding the front section of the fender liner.
  • If equipped with screws, remove them using a Phillips screwdriver #2 (and/or 10mm socket with a 1/4" ratchet depending on fastener style).
  • Pull the liner back just enough to reach the back of the headlamp. Don’t crease the liner hard.

Step 3: Remove the turn signal bulb socket

  • Locate the turn signal socket on the back of the headlamp (usually the outer/lower area of the housing).
  • Twist the socket counterclockwise by hand to unlock it, then pull it straight out.

Step 4: Replace the bulb

  • Pull the old bulb straight out of the socket (wiggle gently if tight).
  • Match the bulb type by reading the number printed on the old bulb base, and install the same type new bulb.
  • Push the new bulb straight into the socket until fully seated.
  • If you accidentally touch the glass, wipe it clean with alcohol and a lint-free cloth before installing.

Step 5: Reinstall the socket and liner

  • Insert the socket back into the headlamp and twist clockwise until it locks.
  • Reposition the fender liner and reinstall all clips/screws using the trim clip removal tool, Phillips screwdriver #2, and/or 10mm socket with 1/4" ratchet.

Step 6: Repeat on the other side

  • Turn the steering wheel fully the other direction and repeat Steps 2–5 for the other front turn signal.
  • Replace bulbs in pairs for color match.

✅ After Repair

  • Turn ignition ON and test left/right turn signals and hazards.
  • Verify the blink rate is normal (fast blinking usually means a bulb isn’t seated or isn’t the correct type).
  • Walk around the front of your Seltos and confirm both sides are equally bright and the same amber color.

💰 DIY vs Shop Cost

Shop Cost: $80-$150 (parts + labor)

You Save: $70-$115 by doing it yourself!

Shop labor rates vary but typically run $100-$150/hour. This repair takes a shop approximately 0.5-1.0 hours.
