⚠️ Safety & Precautions

• ⚠️ Let the headlamp area cool before reaching behind it.
• ⚠️ Support the vehicle with jack stands if you lift it—never rely on a jack alone.
• ⚠️ Keep the smart key 10+ feet away so the car can’t wake up unexpectedly.
• ⚠️ Do not touch the new bulb glass with bare fingers (skin oils can shorten bulb life).

📋 Before You Begin

• Park on level ground and shift to Park.

• If you lift the front corner: chock the rear wheels and place the vehicle securely on jack stands.
• Tip: Do one side at a time.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm the bulb is the problem

• Turn on the hazard lights and walk around the Niro.
• If one front side is out (or flashes fast), that bulb is likely burned out.
• Turn the lights OFF before starting work.

Step 2: Create access at the front wheel well

• Turn the steering wheel to move the tire away from the side you’re working on.
• If you need more space, use a floor jack (rated 2-ton minimum) to lift the front corner and set it on jack stands (rated 2-ton minimum), with wheel chocks at the rear wheels.
• Remove the small wheel-well liner fasteners at the very front edge using a trim clip removal tool and Phillips screwdriver.
• If there are 10mm bolts in that area, remove them using a 10mm socket and 1/4" ratchet.
• Pull the liner back just enough to fit your hand and a flashlight.

Step 3: Remove the turn signal bulb socket

• Reach behind the headlamp and find the turn signal socket (a plastic twist-lock at the outer/front area of the headlamp).
• Twist the socket counterclockwise about 1/4 turn by hand, then pull it straight out.
• If it’s tight, wiggle gently—don’t yank the wiring.

Step 4: Replace the bulb

• Pull the old bulb straight out of the socket using nitrile gloves.
• Push the new Front turn signal bulb (amber 21W, PY21W/BAU15s type) straight into the socket until fully seated.
• Tip: Match the base pins before pushing.

Step 5: Reinstall the socket and liner

• Insert the socket back into the headlamp, then twist clockwise until it locks.
• Reposition the wheel-well liner and reinstall clips/screws using the trim clip removal tool and Phillips screwdriver.
• If you removed 10mm bolts, reinstall them with a 10mm socket and 1/4" ratchet (snug, do not over-tighten).

Step 6: Repeat on the other side (recommended)

• Replace the other front turn bulb the same way.
• Tip: Bulbs often fail close together.

✅ After Repair

• Turn on hazards and verify both front turn signals flash at a normal rate.
• Check that the socket is fully locked—if it’s loose, moisture can get into the headlamp.
• If the new bulb still doesn’t work, the issue may be a fuse, socket, or wiring (tell me which side and what it does).
