Replacing burned-out headlights tends to sneak up on drivers, usually on a dark highway when one beam cuts out. Knowing where to buy headlights, which bulb size your vehicle uses, and whether to upgrade to LED or stick with halogen turns a stressful errand into a quick fix. This guide covers the parts chains, big-box retailers, online marketplaces, and dealer counters that actually stock what you need, plus what to look for so you do not waste money on a bulb that fails in six months.

What Headlights Are and Who Needs to Replace Them
Vehicle headlights are the forward-facing lighting system that lets you see the road and lets oncoming traffic see you. The term covers two related parts: the bulb itself (halogen, LED, or HID/xenon) and the housing assembly that holds the bulb, reflector, and lens. Most replacements are simple bulb swaps, but cracked lenses or moisture intrusion can mean a full assembly is needed. Federal DOT rules require every passenger vehicle to have two functioning low beams and two high beams, so a single burned-out bulb is a fix-it ticket waiting to happen.
Anyone who drives at night, in fog, or heavy rain needs both beams at full output. Halogens last 450 to 1,000 hours, LEDs claim 30,000+ hours, and HID kits sit in between. According to NHTSA regulations on aftermarket lighting, replacement bulbs and assemblies must meet DOT compliance standards, marked with a “DOT” stamp on the lens or packaging.
What to Look For: Bulb Type, Fitment, and Build Quality
Bulb size and fitment. The single most important spec is the bulb code: H7, H11, 9005 (HB3), 9006 (HB4), 9012, H13, and 9008 are the most common. Your owner’s manual lists the exact codes for low beam, high beam, and fog lamps. A 9005 will not fit an H11 socket, and forcing the wrong base damages the wiring harness.
Light technology. Halogen is the OEM standard on most vehicles built before 2018, cheap and instantly compatible. LED conversion kits offer brighter output and a cooler 5,000K to 6,500K daylight white. HID/xenon kits produce the brightest beam pattern but require a ballast and longer warm-up.
DOT compliance and street legality. Aftermarket LED conversion kits installed in a halogen reflector housing are not DOT-approved for on-road use in many states, though enforcement varies. Look for “DOT-compliant” or “SAE-certified” on the box if the bulb will face annual inspection.
Color temperature and lumens. Stock halogen runs around 3,200K (warm yellow); pure white sits at 5,000K to 6,000K. Anything above 8,000K shifts blue or purple and throws less usable light. Lumens matter more than color: 1,500 lm per bulb is the OEM baseline, quality LED kits push 6,000 to 12,000 lm per pair.
OEM versus aftermarket assemblies. A factory assembly from the dealer fits perfectly but costs two to four times more than a quality aftermarket unit. Brands like Depo, TYC, and Anzo make CAPA-certified assemblies at a fraction of the price.
Housing compatibility. Reflector housings (older vehicles) and projector housings (newer cars and trucks) have different optics. An LED designed for a projector may produce dangerous glare in a reflector setup. Match the bulb to the housing type listed in the product description.
What to Avoid When Buying Headlights
Generic “10,000K super white” no-name bulbs. The blue-tinted bulbs sold for $15 a pair on marketplaces almost always emit fewer real lumens than a stock halogen. Color temperature numbers above 8,000K mean less visibility, not more. Skip the gimmick.
LED swaps in reflector housings without proper optics. Cheap LED conversions in reflector cars scatter light into oncoming drivers’ eyes and leave dark spots on the road. Choose a kit engineered for reflector housings or retrofit a projector housing instead.
Counterfeit Philips and Sylvania boxes. Marketplaces sometimes ship suspiciously cheap premium bulbs that are repackaged knockoffs. Buy from authorized sellers like AutoZone, RockAuto, or Amazon-shipped (not third-party-fulfilled) listings.
Skipping the pair replacement. Bulbs from the same set degrade together. If one side burns out, the other is days behind. Replace both at once so the beam pattern matches.
Ignoring the housing condition. A new bulb in a yellowed, crazed lens still throws weak, scattered light. Restore the lens or replace the assembly before blaming the bulb.
Where to Buy Headlights at Local Stores
AutoZone
AutoZone is the deepest in-stock parts chain in North America. Walk in with your year, make, and model and a counter rep pulls the right bulb code from their lookup system. Stores carry Sylvania, Philips, and house-brand Duralast options, plus full assemblies for popular vehicles. Free in-store install on accessible bulbs is genuinely useful. Browse the AutoZone selection to confirm fitment first.
O’Reilly Auto Parts
O’Reilly stocks similar inventory and competes hard on price. Counter staff tend to be longtime auto parts people who can talk through whether you need just the bulb or the full housing. Ask about the lifetime warranty on certain Sylvania and Philips lines.
Advance Auto Parts and NAPA
Advance Auto Parts runs frequent online coupons (often 20 to 30 percent off) that beat in-store sticker prices, so check the site before ordering for in-store pickup. NAPA Auto Parts stores lean toward professional installers and stock heavier-duty options for trucks, fleet vehicles, and older models that other chains have stopped carrying. Pep Boys covers similar ground in markets where NAPA is thin.
Walmart
The automotive aisle at Walmart stocks Sylvania, Philips, and Bosch bulbs at noticeably lower prices than parts chains, especially on multi-pack value boxes. Selection skips the more obscure bulb codes, but the common H11, 9005, 9006, and H7 fitments are always on the rack. Costco and Sam’s Club occasionally carry premium twin-packs (Sylvania SilverStar, Philips CrystalVision) at warehouse pricing if you want to stock spares.
Can You Buy Headlights at Target?
Target carries a tiny rotating selection of common bulb sizes in the automotive aisle, mostly Sylvania basic halogens. Selection is too thin to count on for a same-day fix, so treat it as a backup if the parts chains are closed.
Your Car Dealership
The dealer parts counter is the right call for OEM assemblies on newer vehicles, especially adaptive LED units and anything with integrated turn signal modules. Expect to pay a premium, but you get exact factory fitment. Call ahead; dealers usually order assemblies overnight.
Where to Buy Headlights Online
Amazon
Amazon has the widest selection by far: every bulb size, every brand, plus LED conversion kits, HID systems, and full aftermarket assemblies. Filter by your vehicle through the “Garage” tool to avoid fitment guesswork. Read recent reviews carefully on LED kits, the cheap ones often arrive with mismatched color temperatures across the pair.
RockAuto
RockAuto wins on price for full assemblies and obscure bulb codes. The catalog interface is utilitarian but unbeatable for older vehicles, and shipping is fast. Confirm the part number against your VIN before ordering; returns on heavy housings are a hassle.
Champion Auto Parts and Manufacturer Sites
Champion sells direct through their site and through retailer partners, with a handy store finder for nearby stockists. Sylvania.com and Philips Automotive both run brand stores with promotional bundles you will not see at retail. For LED kit specialists, Lasfit and Hikari sell direct from their own sites with tighter quality control than third-party listings.

Tips for Replacing Headlights Yourself
- Wear nitrile gloves or hold the bulb by its plastic base. Skin oil on the glass envelope shortens life dramatically.
- Disconnect the battery negative terminal first near electrical connectors. A car battery in good shape matters, voltage drops cause bulbs to flicker.
- Replace bulbs in pairs even if only one burned out, so the beam pattern stays balanced.
- Aim the beam against a garage door at 25 feet after install. The hot spot should fall just below bulb level.
- Use bulb-specific lookup tools on retailer sites to confirm the code; owner’s manuals sometimes list discontinued part numbers.
- For full assembly swaps, expect 30 to 90 minutes per side and possibly removing the bumper cover on newer cars.
Frequently Asked Questions About Headlights
How much does it cost to replace headlights?
A pair of basic halogen bulbs runs $15 to $30. Premium halogens land $35 to $60. Quality LED conversion kits sit at $40 to $120. Full OEM assemblies range from $150 to $800 depending on the vehicle, and adaptive matrix units on luxury cars can top $1,500 per side. Labor at a shop adds $30 to $90 per side for bulbs, more for assembly swaps.
How long do headlights last?
Standard halogens last 450 to 1,000 hours of use, roughly two to four years for a daily driver. Premium halogens often die sooner, the brighter filament burns hotter. LED bulbs claim 25,000 to 50,000 hours but real-world life is closer to 5,000 to 15,000 hours due to heat in the housing. HID/xenon sits in between at 2,000 to 4,000 hours.
Can I replace headlights myself or do I need a mechanic?
Most bulb swaps on vehicles built before 2015 are 10-minute jobs from the engine bay with no tools. Newer cars often require removing the air intake or even the bumper to reach the bulb, which pushes the job into the one-hour range and may justify paying a shop. Full assembly replacement is usually intermediate-difficulty DIY for anyone comfortable with a socket wrench.
Are LED headlight conversions legal?
Federal DOT rules technically require LED bulbs to be installed only in housings certified for them, which means most aftermarket LED swaps in halogen housings are not strictly legal for road use. State enforcement varies widely, some states fail vehicles at inspection for non-DOT bulbs while others ignore it. Check your state inspection rules before installing, especially if you live in California, New York, or Massachusetts.
How do I know which headlight bulb fits my car?
Check the owner’s manual under “bulb specifications” or “lamp replacement,” look at the existing bulb’s base for a printed code (H7, H11, 9005, etc.), or use the year-make-model lookup on AutoZone, O’Reilly, or RockAuto sites. The same vehicle may use different bulbs for low beam, high beam, and fog lamps, confirm each one separately.
