⚠️ Safety & Precautions

• ⚠️ Turn headlights OFF and let bulbs cool 10+ minutes (they get extremely hot).
• ⚠️ Do not touch the new bulb’s glass with bare fingers; skin oil can shorten bulb life. If you do touch it, clean with rubbing alcohol and a lint-free towel.
• ⚠️ Keep the key out of the ignition while working near the fan and belts.
• 🔋 Battery disconnect is not required, but it’s okay to disconnect the negative terminal if you want extra safety.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Identify which bulb you’re replacing (Low vs High beam)

• Use a flashlight to look behind the headlamp assembly.
• The two headlight bulbs are the low beam (9006) and high beam (9005). They twist-lock into the housing.

Step 2: Remove the electrical connector

• Put on nitrile gloves and safety glasses.
• Grip the connector at the back of the bulb and pull it straight off.
• If it’s tight, wiggle gently while pulling—don’t pull on the wires.

Step 3: Remove the old bulb

• Hold the bulb base and rotate it counterclockwise about 1/4 turn.
• Pull the bulb straight out of the headlamp housing.

Step 4: Install the new bulb

• Keep the new bulb in your gloved hand (avoid touching the glass).
• Optional: apply a tiny amount of dielectric grease to the connector seals (not on the bulb glass).
• Insert the bulb into the housing, align the tabs, then twist clockwise until it locks.

Step 5: Reconnect the electrical connector

• Push the connector onto the bulb until it seats fully.

Step 6: Repeat on the other side (and for the other beam, if you’re doing both)

• Use the flashlight and repeat Steps 2–5 for the matching bulb on the other headlamp.
• Repeat again if you’re also replacing the other beam (high or low).

Step 7: Reconnect the battery (if disconnected)

• Reinstall the negative terminal and tighten using a 10mm socket with a ratchet until snug.

✅ After Repair

• Turn headlights ON and verify: low beams work, high beams work, and both sides match in color/brightness.
• With the lights on, gently tap around the connector area by hand to confirm there’s no flicker (loose connector check).
• If one side still doesn’t work, swap the left/right bulb (quick test) to confirm if it’s a bulb issue or a vehicle wiring issue.
