Whether you drive a compact car, a heavy-duty truck, or a classic vehicle, their inventory includes bulbs compatible with nearly every make and model, from Toyota Camrys to Ford F-150s.

Not sure if your car needs a 9003 or an H11 bulb? AutoZone’s certified parts associates are trained to help. They’ll ask for your vehicle’s make, model, year, and even your VIN (vehicle identification number) to pull up the exact bulb specifications. No more guessing games or buying the wrong part.

3. Convenience at Every Step
Need a bulb today? Use AutoZone’s “Check Inventory” tool online to see if your local store has your bulb in stock. If not, they offer same-day delivery via their Shipt service or ship directly to your home. For those who prefer professional help, many locations provide free installation with bulb purchases—no appointment needed.

Step 1: Determine the Right Headlight Bulb for Your Vehicle

The first mistake most drivers make is assuming all headlight bulbs are interchangeable. They’re not. Using the wrong bulb can lead to poor visibility, electrical issues, or even damage to your vehicle’s lighting system. Follow these steps to find your perfect match:

Check Your Owner’s Manual
Your vehicle’s owner’s manual is the ultimate resource. Flip to the “Lighting” or “Electrical” section, and you’ll find the exact bulb type (e.g., H11, 9006) and wattage (usually 55W or 60W for halogen bulbs) specified by the manufacturer. Keep this handy when shopping.

Use Your VIN to Confirm
If you don’t have your manual, AutoZone’s website or mobile app can help. Enter your vehicle’s VIN (located on your driver’s side dashboard or insurance card) into their “Find My Part” tool. The system will automatically generate the correct bulb part number, eliminating guesswork.

Understand Bulb Types
Headlight bulbs fall into three main categories. Here’s what you need to know:

  • Halogen Bulbs: The most common type, halogens use a tungsten filament heated by an electric current to produce light. They’re affordable (30), easy to replace, and widely available. However, they’re less energy-efficient than newer options and take a few seconds to reach full brightness.

  • Xenon (HID) Bulbs: High-intensity discharge (HID) bulbs produce light by ionizing xenon gas. They’re brighter (up to 3x more than halogens), last longer (2,000–3,000 hours vs. 500–1,000 for halogens), and emit a whiter light that improves nighttime visibility. They’re pricier (150) but worth the investment for drivers who prioritize safety.

  • LED Bulbs: Light-emitting diode (LED) bulbs are the newest option. They use semiconductors to convert electricity into light, making them ultra-efficient (up to 50,000 hours of life), instant-on, and cooler-running than halogens or HIDs. LEDs also produce a crisp, white light that closely mimics natural daylight. While they cost more upfront (200), their longevity makes them a cost-effective choice over time.

Consider Local Regulations
Some states restrict aftermarket headlights due to brightness or color temperature. For example, California requires headlights to emit a white light with a color temperature between 4,300K and 6,500K. AutoZone’s parts team can help you select bulbs that comply with local laws to avoid fines.

Step 2: Purchase Your Headlight Bulb at AutoZone

Once you’ve identified the right bulb, head to your local AutoZone or shop online. Here’s how to streamline the process:

Shop In-Store
AutoZone’s physical stores are designed for convenience. Use their self-checkout kiosks or ask a parts associate for assistance. If you need help installing the bulb, simply ask—they’ll gladly set up an appointment with one of their certified technicians. Most installations take 10–15 minutes and are free with purchase.

Order Online for Home Delivery
AutoZone’s website and app let you browse thousands of bulbs, read customer reviews, and compare prices. Look for deals like “Buy 2, Get 1 Free” on select halogen bulbs, or bundle your purchase with other auto essentials (wiper blades, air filters) for extra savings. Orders over $49 qualify for free shipping to your home or local store.

Take Advantage of Warranties
All AutoZone headlight bulbs come with a limited warranty. If your bulb burns out prematurely (within 12–24 months, depending on the type), bring the receipt back to the store, and they’ll replace it free of charge. Premium brands like Sylvania offer extended warranties—ask your parts associate for details.

Step 3: Install Your New Headlight Bulb Safely

Installing a headlight bulb is simpler than most people think, but it’s critical to do it correctly to avoid damaging your vehicle or compromising visibility. Follow these steps:

Gather Your Tools
You’ll need:

  • A clean microfiber cloth
  • Latex or nitrile gloves (to avoid touching the bulb’s glass with oils from your skin)
  • A pair of needle-nose pliers (optional, for stubborn bulb holders)

Safety First

  • Turn off your vehicle and let the engine cool completely. Hot bulbs can burn your hands.
  • Park on a flat, well-lit surface. Engage the parking brake and turn on your hazard lights.

Remove the Old Bulb

  1. Open the hood and locate the headlight assembly. Most vehicles have a plastic cover or clip securing the assembly—gently pry it off with a flathead screwdriver (be careful not to crack the plastic).
  2. Disconnect the electrical connector from the back of the old bulb. Twist it counterclockwise and pull straight out.
  3. Remove the old bulb. Halogen bulbs are held in place by a spring-loaded clip; gently push the clip down and slide the bulb out. HID and LED bulbs may require removing screws or retaining rings—refer to your owner’s manual for specifics.

Install the New Bulb

  1. Handle the new bulb by its plastic base only—never touch the glass with your bare hands. Oils can cause hot spots, reducing the bulb’s lifespan.
  2. Align the bulb’s pins with the socket’s slots. Push the bulb into place until it clicks. For halogen bulbs, ensure the spring clip snaps back into position.
  3. Reconnect the electrical connector. Twist it clockwise to lock it in place.
  4. Replace the headlight assembly cover and tighten any screws or clips.

Test the Lights
Turn on your headlights and high beams to check for proper operation. If one bulb is dimmer than the other, double-check the connection—you may have missed a step.

Common Headlight Problems and How AutoZone Can Help

Even with the right bulb, headlight issues can arise. Here’s how to troubleshoot them:

Problem: Bulb Doesn’t Light Up

  • Cause: A blown fuse, faulty wiring, or a loose connection.
  • Solution: Check your vehicle’s fuse box (located under the dashboard or hood) for a blown headlight fuse. If the fuse is good, use a multimeter to test the wiring for voltage. If you’re not comfortable with electrical work, AutoZone’s technicians can diagnose and fix the issue.

Problem: Bulb Flickers or Dimms

  • Cause: Corroded sockets, a failing alternator, or a low-quality bulb.
  • Solution: Clean the socket with a wire brush and dielectric grease to prevent corrosion. If the problem persists, have your alternator tested (AutoZone offers free battery and charging system checks). Switching to a higher-quality bulb (like Sylvania) often resolves flickering.

Problem: Bulb Burns Out Too Quickly

  • Cause: Using the wrong wattage, touching the glass with bare hands, or a voltage regulator issue.
  • Solution: Ensure you’re using the manufacturer-recommended wattage. Always handle bulbs with gloves. If the issue continues, have your vehicle’s electrical system inspected—AutoZone can help with that too.

Maintain Your Headlights for Long-Lasting Performance

Proper maintenance extends the life of your headlight bulbs and keeps your vehicle safe on the road:

  • Clean Your Headlights Regularly: Dirt, bugs, and oxidation can block light output. Use a headlight restoration kit (available at AutoZone) to remove yellowing and restore clarity.
  • Inspect Bulbs Monthly: Check for cracks, corrosion, or loose connections. Catching issues early prevents more expensive repairs.
  • Replace Both Bulbs at Once: If one bulb burns out, replace both. Mismatched bulbs can strain your vehicle’s electrical system and reduce visibility.
