⚠️ Safety & Precautions

• ⚠️ Turn headlights OFF and let bulbs cool before touching them.
• ⚠️ Wear gloves and do not touch the new bulb glass; skin oil can shorten bulb life.

📋 Before You Begin

• Park on level ground, shift to Park, and set the parking brake.
• Open the hood and support it securely.
• Decide if you want to disconnect the battery (optional): use a 10mm socket to loosen the negative terminal and move it aside so it can’t spring back.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm which bulb you’re replacing

• Your Frontier’s main headlight bulb is a dual-beam bulb (low and high beam in one bulb) typically H13/9008.
• If you want, tell me: are you replacing the main headlight bulbs (low/high) or the small parking/turn bulbs? I can tailor the steps.

Step 2: Access the back of the headlamp (passenger side first)

• Use a flashlight to locate the bulb socket at the back of the passenger headlamp.
• If space is tight, remove the intake snorkel/duct fasteners using a 10mm socket, 3/8" ratchet, and 3" extension, then move the duct slightly for hand room.
• Use a flat trim tool to gently pop any push-clips if equipped.
• Tip: Take a quick photo before unplugging.

Step 3: Unplug the headlight connector

• Put on nitrile gloves and safety glasses.
• Press the locking tab on the connector and pull it straight off the bulb.
• If it’s stubborn, wiggle gently while holding the connector (not the wires).

Step 4: Remove the old bulb

• Grab the bulb’s plastic base and twist it counterclockwise to unlock it.
• Pull the bulb straight out of the housing.
• Use the flashlight to confirm the bulb’s 3 locating tabs match the housing slots.

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

• Still wearing nitrile gloves, insert the new bulb into the housing, lining up the tabs.
• Twist clockwise until it stops and feels fully locked.
• Apply a very small amount of dielectric grease inside the connector seal (not on the bulb glass).

Step 6: Reconnect and test (before reassembly)

• Plug the connector back on until it clicks.
• If you disconnected the battery, reinstall the negative terminal using a 10mm socket.
• Turn the headlights on and confirm low beam and high beam work on that side.

Step 7: Repeat on the driver side

• Use the flashlight to locate the driver-side bulb at the back of the headlamp.
• Repeat: unplug connector, twist bulb out, install new bulb, reconnect, and test.

Step 8: Reinstall any ducts/clips you moved

• Reposition the intake duct and reinstall fasteners using a 10mm socket, 3/8" ratchet, and 3" extension.
• Reinstall any push-clips by pressing them in by hand (use the flat trim tool only if needed).

✅ After Repair

• Check low beams and high beams on both sides.

• Take a short night drive and confirm you have good road lighting without blinding oncoming traffic.
