🔧 1500 - Headlight Bulb Replacement (Both Sides)

On your 1500, the headlight bulbs twist-lock into the back of the headlamp housing. The main “gotcha” is that there are two factory headlamp styles, and the bulb types differ—so we’ll cover both paths.

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

⚠️ Safety & Precautions

• ⚠️ Turn headlights OFF and let bulbs cool 10-15 minutes (they get extremely hot).
• ⚠️ Wear gloves and do not touch the new bulb glass with bare fingers (skin oils can shorten bulb life).
• ⚠️ Support the hood securely and keep keys out of the ignition while working.

📋 Before You Begin

• Park on level ground, shift to Park, and set the parking brake.
• Open the hood and use a flashlight to look at the back of one headlamp housing.
• Identify your headlamp style:
  • Quad headlamps: two separate bulbs per side (one high beam, one low beam).
  • Dual headlamps: one main bulb per side (does both high and low).
• Quick question (so I can tell you the exact bulb set to buy): do you have quad (two bulbs per side) or dual (one bulb per side) headlights?

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Make sure you’re replacing the correct bulb(s)

• Turn the headlight switch ON briefly, then OFF.
• Verify which function is out (low beam vs high beam) by watching the light pattern.
• Replace left and right bulbs together.

Step 2: Access the rear of the headlamp housing

• Stand at the fender and look behind the headlamp housing.
• If space is tight, remove the closest intake duct cover/air inlet pieces using an 8mm socket, 10mm socket, 1/4" ratchet, and trim clip removal tool.
• A trim clip tool is a small forked tool that pops plastic push-clips out without breaking them.

Step 3: Disconnect the bulb electrical connector

• Press the locking tab and pull the connector straight off the bulb.
• If it’s stubborn, wiggle gently—don’t pull on the wires.

Step 4: Remove the bulb from the headlamp

• Grab the bulb base and rotate it about a quarter-turn counterclockwise by hand.
• Pull the bulb straight out.

Step 5: Install the new bulb

• Put on nitrile gloves before handling the new bulb.
• Insert the new bulb into the housing, aligning the tabs.
• Rotate the bulb clockwise until it locks fully in place.
• Reconnect the electrical connector until it clicks.
• If using dielectric grease, apply a tiny dab inside the connector seal area (not on the bulb glass).

Step 6: Repeat for the other side (and other bulb if quad-style)

• Repeat Steps 2-5 on the other headlamp.
• If you have quad headlamps, repeat for both the low beam bulb and high beam bulb (each side) as needed.

Step 7: Reinstall any intake/trim pieces you removed

• Reinstall ducts/covers and push-clips using the trim clip removal tool.
• Tighten any bolts snugly using the 8mm socket or 10mm socket (hand-tight; do not over-tighten plastic parts).

✅ After Repair

• Turn the headlights ON and verify both sides work on low beam and high beam.
• At night, park 20-25 feet from a wall and confirm both beams look even (no obvious “one side higher” issue).
• If a new bulb doesn’t light, re-check the connector is fully clicked and the bulb is fully twist-locked.
