AutoZone will install a headlight bulb you buy from them, but not headlight assemblies, and the service is free only if you purchase the bulb there
AutoZone offers free headlight bulb installation at most locations if you buy the bulb from AutoZone. A technician will remove the old bulb, insert the new one, and test it — the whole process usually takes 10 to 15 minutes. This applies to standard halogen bulbs, HID bulbs, and LED bulbs that screw or clip into an existing housing.
AutoZone does not replace the headlight assembly itself — the plastic or metal housing that holds the bulb. If your headlight lens is cracked, the housing is damaged, or the entire unit has failed, you will need to buy a replacement assembly and have a mechanic or dealership install it. AutoZone can sell you the assembly, but installation is not part of their in-store service.
If you bring your own bulb from another retailer or supplier, AutoZone will not install it. Some locations may make exceptions, but the standard policy is that the installation is a courtesy tied to the purchase. Call your local AutoZone before you arrive to confirm their specific policy, because practices vary slightly by store and region.

What AutoZone will and will not do
AutoZone's in-store service is limited to bulb installation. They will remove your old headlight bulb, install a new one, and turn on your headlights to make sure it works. This covers all bulb types: standard halogen H7, H11, or 9005 bulbs; HID (xenon) bulbs; and LED bulbs designed to fit your vehicle's existing socket.
AutoZone will not touch the headlight housing, lens, or assembly. If your headlight is dim because the lens is cloudy or oxidized, they cannot restore it. If the housing is cracked or the bulb socket is damaged, they cannot repair it. If the entire headlight unit has failed electrically, they cannot replace it. In those cases, you need a mechanic, dealership, or body shop.
AutoZone also will not install bulbs for fog lights, interior dome lights, or other vehicle lighting — only headlights. And they will not install a bulb if you did not buy it from AutoZone, with rare exceptions that depend on the individual store manager's discretion.
How to get your headlight bulb installed
Walk into any AutoZone location with your vehicle keys and the bulb you want installed. Tell a staff member you need a headlight bulb installed. They will ask which headlight (driver or passenger side) and may ask you to pop your hood so they can see the socket type and confirm the bulb fits.
The technician will remove the old bulb by twisting or unclipping it, depending on your vehicle's design. They will insert the new bulb, close the headlight housing, and turn on your headlights to confirm the new bulb lights up. If it does not, they will troubleshoot — sometimes the bulb is defective, or the socket needs cleaning.
The entire process takes 10 to 15 minutes. You do not need an appointment. If the store is busy, you may wait 20 to 30 minutes. There is no charge for the labor.
Buying the right bulb before you go
Before you visit AutoZone, you need to know your vehicle's headlight bulb type. The easiest way is to check your owner's manual — it will list the bulb size and type for each light on your vehicle. You can also search your vehicle's year, make, and model on AutoZone's website, and their system will show you the correct bulb.
Headlight bulbs come in different sizes and bases. Common types include H7, H11, H13, 9005, and 9006. Some vehicles use two different bulbs — one for low beam and one for high beam. If you buy the wrong size, it will not fit the socket, and the technician will not be able to install it.
AutoZone stocks halogen bulbs, HID bulbs, and LED bulbs. Halogen bulbs are the cheapest and most common. LED bulbs cost more but last longer and produce a brighter light. HID bulbs are less common in newer vehicles but are still available. Ask a staff member which type is right for your vehicle if you are unsure.
When you need a mechanic instead
If your headlight does not turn on after the bulb is installed, the problem is likely electrical — a bad socket, a blown fuse, or a wiring issue. AutoZone cannot diagnose or repair these problems. You will need to take your vehicle to a mechanic or dealership.
If your headlight lens is cloudy, yellowed, or cracked, you need a new headlight assembly. AutoZone sells replacement assemblies for most vehicles, but you will need a mechanic or dealership to remove the old one and install the new one. The assembly usually bolts to the front of the vehicle, and installation requires removing trim pieces and sometimes the bumper.
If both headlights are dim or flickering, the issue may be a failing alternator or battery, not the bulbs. A mechanic can test your electrical system and tell you what needs to be replaced.
Cost comparison: AutoZone versus other options
A headlight bulb at AutoZone costs between $5 and $25 depending on the type. Halogen bulbs are usually $5 to $15. LED bulbs are typically $15 to $25. HID bulbs can cost $20 to $40. The installation is free.
If you go to a dealership, they will charge you for the bulb and for labor. Dealership labor rates vary widely, but you can expect to pay $50 to $150 for headlight bulb installation on top of the bulb cost. A mechanic's shop will usually charge less — $20 to $50 for labor — but you still pay for both the bulb and the work.
If you install the bulb yourself, you pay only for the bulb. Many vehicles have headlights that are straightforward to access and replace without tools. Your owner's manual will tell you if your vehicle is one of them. If you are not comfortable working on your vehicle, the free installation at AutoZone is the cheapest option.
What to bring and what to expect
Bring your vehicle keys and your vehicle. You do not need to bring paperwork or proof of purchase. If you know your vehicle's year, make, and model, tell the staff member — it helps them confirm the bulb type. If you do not know it, they can usually look it up from your license plate or by looking at your vehicle.
Wear clothes you do not mind getting dirty. The technician may brush against your vehicle's exterior, and headlight housings can be dusty. The work is done in the parking lot or in the store's service bay, depending on the location.
If the bulb does not work after installation, tell the technician when ready. They can try a different bulb or troubleshoot the socket. If the problem is electrical, they will tell you that you need a mechanic.
Frequently Asked Questions
Can I bring my own bulb from another store?
AutoZone's standard policy is no — they install only bulbs you buy from them. Some individual store managers may make exceptions, but you cannot count on it. Call your local AutoZone before you go to ask about their specific policy.
Do I need an appointment?
No. Walk in during business hours and ask for headlight bulb installation. If the store is busy, you may wait, but most installations take 10 to 15 minutes. Call ahead if you want to know how busy they are.
What if the new bulb does not work?
Tell the technician right away. They will try another bulb to rule out a defective one. If a second bulb does not work, the problem is likely electrical — a bad socket, blown fuse, or wiring issue — and you need a mechanic.
Can AutoZone replace my entire headlight assembly?
AutoZone sells replacement assemblies but does not install them. You will need a mechanic or dealership to remove the old assembly and bolt on the new one. This usually takes one to two hours and costs $100 to $300 in labor, depending on your vehicle.
What if my vehicle has HID or LED headlights from the factory?
AutoZone can replace HID and LED bulbs if they are the type that screw or clip into the existing housing. If your vehicle has a sealed LED or HID unit that cannot be opened, you need a replacement assembly and a mechanic to install it.
