One beam dies on a dark two-lane road and the errand cannot wait. Knowing where to buy headlights, which size code your vehicle takes, and whether an LED swap is worth it turns that into a cheap fix instead of a shop visit.

What Headlights Do and Who Should Buy Them
Headlights are the forward-facing part of a car’s automotive lighting system, built to light the road ahead and keep the vehicle visible to oncoming vehicles. Two purchases hide behind the one word: the replaceable light source, and the shell that holds it behind a lens. Most jobs swap the source alone. A cracked lens or standing water inside means the whole unit gets replaced.
Federal Motor Vehicle Safety Standard 108 covers the headlamp system a carmaker certifies, and it incorporates SAE performance requirements. Parts certified to it carry a DOT marking. State law is what bites day to day: in most states both low beams have to work, so one dead side is a fix-it ticket waiting to happen. Anyone doing real night driving, or running a pickup through fog, snow and ice, wants full output on both sides. NHTSA publishes the equipment rules.
Features Worth Paying For in Headlights
Start with the size code stamped on the base of the part you are pulling. Five things separate a replacement headlight worth buying from a gimmick.
Size code and fitment. H7, H11, 9005 (HB3), 9006 (HB4), 9012, H13, and 9008 cover most cars and trucks on US roads. A 9005 will not seat in an H11 socket, and forcing the wrong base cracks the connector. European fitments on BMW, Mercedes-Benz, and Porsche often use H7; many Nissan, Subaru, and Hyundai models run H11. Confirm by VIN, or by year, make, and model.
Light technology. Halogen is standard equipment on most vehicles built before the late 2010s: cheap, warm white, instantly compatible. LED headlights, built around light-emitting diode packages, run whiter and draw less current. HID/xenon throws an intense beam of light but needs a ballast and a moment to reach full brightness.
Housing type: reflector or projector. A reflector bowl bounces light off a mirrored surface. Projector technology sends it through a small lens with a hard cutoff along the top edge. A source built for one set of optics scatters glare in the other, which is what blinds oncoming drivers.
Color temperature, not lumen claims. Stock halogen sits near 3,200K; 5,000K to 6,000K reads as pure white. Above about 8,000K the output shifts blue and puts less usable light on the pavement. Advertised lumen figures are often measured at the bare emitter, not out of the finished part.
OEM or aftermarket assemblies. A dealer part fits exactly and costs the most. Depo, TYC, and Anzo are the common replacement brands, and some of their lighting carries CAPA certification, granted per part number rather than per brand.
Sealed beam, classic cars, and the 5.75-inch problem
Older vehicles use sealed beam units, where the parabolic aluminized reflector, filament, and lens are one glass part you replace whole. Round 7-inch and 5.75-inch sizes fit many classic car and early Jeep applications, and chrome trim reproductions are still made. If your Ford, Dodge, or Volkswagen predates the 1990s, search by diameter.
How Much Should You Pay for Headlights
As of July 2026, a basic halogen pair runs about $15 to $30, premium halogens $35 to $60, and quality LED kits $40 to $120. A complete unit starts near $150 and reaches $800 or more, with adaptive matrix units on luxury models costing far more per side. Shop labor adds $30 to $90 per side.
| Tier | Price | What changes |
|---|---|---|
| Budget | $15 to $30 a pair | Stock-equivalent halogen, factory brightness, shortest life |
| Mid-range | $35 to $120 | Premium halogen or a name-brand diode kit with real heat management |
| Premium | $150 and up | Complete unit, projector or adaptive optics, factory fitment |
Paying more is wasted when the shell is the actual problem. A premium lamp behind a yellowed, crazed lens still throws scattered light, and a cheap restoration kit buys back more visibility than upgrading the pair inside.
Ordering Headlights Online: Where and Why
Online is where the selection lives: every size code, LED upgrade kits, HID systems, and headlight assemblies no local shelf carries.
Amazon
Amazon carries the widest headlight catalog of the lot, including odd fitments that never reach retail shelves. Use the vehicle Garage filter, and read the newest reviews on any conversion kit, watching for what buyers say about color match between the two sides of a pair. Browse the current listings.
RockAuto
RockAuto wins on price for complete units and discontinued part numbers, the default for anything older than about fifteen years. Match the part number to your VIN first, since sending a large unit back costs shipping both ways.
eBay, Champion, and buying brand direct
eBay is worth a look for used OEM units pulled from salvage vehicles, often at a fraction of dealer pricing. Champion Auto Parts sells its lighting range direct and lists stockists through a store finder. Sylvania and Philips Automotive run brand stores with bundles retail does not get, and specialists including Lasfit and Hikari ship direct.
Finding Headlights Near You: In-Store Options
Five chains cover almost every US ZIP code, and each will look up your year, make, and model at the counter.
AutoZone
AutoZone keeps deep walk-in lighting stock: Sylvania, Philips, and house-brand Duralast, plus complete units for common vehicles. Some locations handle installation of an easy-access part, so ask at the counter. Check their catalog to confirm the code first.
O’Reilly Auto Parts
O’Reilly stocks comparable inventory and competes on price. Their counter lookup covers fog and high beam codes too, which saves a second trip if you do all four corners at once. Tail lights sit in the same aisle.
Advance Auto Parts, NAPA, and Pep Boys
Advance Auto Parts runs online-only promo codes that can undercut its own shelf price, so price the part on the site first and pick it up in store. NAPA Auto Parts leans professional and stocks heavier-duty lighting for trucks and fleets. Pep Boys fills the same role where NAPA is thin.
Walmart, Target, and the warehouse clubs
The Walmart automotive aisle prices the common codes (H11, 9005, 9006, H7) below the parts chains and stocks Sylvania, Philips, and Bosch. Obscure sizes are not there. Target keeps a thin rotating selection of basic halogens, a backup rather than a plan. Costco and Sam’s Club stock varies by club.
Your dealership
The dealer counter is the right call for OEM headlamp assemblies on newer vehicles, especially adaptive units and anything with an integrated turn signal or daytime running light (DRL) module. Call ahead, since these are usually ordered in.
What Not to Buy: Common Headlight Pitfalls
The most expensive mistake is shopping color temperature instead of beam quality.
No-name 10,000K blue bulbs. The blue-tinted pairs sold cheap on marketplaces put less usable light on the road than the stock halogen you are replacing. A higher color number is not more brightness.
Conversion kits dropped into halogen optics. An emitter shaped nothing like a filament sits in the wrong focal point, throwing light upward and leaving dark patches ahead. Buy a kit engineered for your housing type.
Suspiciously cheap premium boxes. Counterfeit Philips and Sylvania packaging turns up on marketplaces. Order from a parts chain, from RockAuto, or from a listing shipped and sold by Amazon.
Replacing one headlight only. Both sides aged together, so the survivor is weeks behind. Doing the pair keeps the beam pattern even and saves a second teardown.
Buying looks instead of light. Halo rings, RGB accents, and blacked-out shells from brands like Oracle change how the front end looks without improving what you see, and many styling parts skip DOT marking. If cosmetics are the goal, put the money into trim you can see in daylight, like the wheel covers in our hubcaps guide.
Doing the swap without ruining the new pair
- Read the code off the old part, not just the manual, since printed guides list discontinued numbers.
- Let it cool, then unplug the connector before twisting the retainer.
- Handle glass with a clean nitrile glove. Skin oil bakes onto a halogen envelope and shortens its life.
- Seat the retainer fully, reconnect, and test both beams before closing the hood.
- Compare the new cutoff on a flat wall against where the old one fell, then adjust the aim screws if it sits high.
Older cars are a minutes-long job from the engine bay. Newer sedans and SUVs may need the air intake or bumper cover out of the way, which is where paying a shop pencils out. A weak battery makes a fresh pair flicker, so check our Interstate Batteries guide if yours is aging.
Top Headlight Bulbs Worth Buying
These five were chosen by comparing published specs, weighted toward name-brand heat management and DOT marking rather than advertised brightness.
Best premium halogen: Philips X-tremeVision Pro150. Philips rates it up to 150 percent brighter than a standard halogen, with no socket changes. Sold in H7, H11, 9005, and 9006. About $35 to $50 a pair. Check price on Amazon
Best conversion kit for H11: Hikari Ultra LED. Advertised at 12,000 lm per pair at 6,000K, with a copper-core heat sink. Plug-and-play on most H11 vehicles. About $60 to $90. Check price on Amazon
Best budget kit: Fahren H11 LED headlight bulbs. Advertised near 10,000 lm per pair at 6,500K, CanBus-ready on many cars so the dash does not throw an error. About $25 to $40. Check price on Amazon
Best H7 for European fitments: Lasfit LSplus. Marketed for the H7 sockets common on Volkswagen, BMW, and Audi, with a short heat sink for tight engine bays. About $50 to $70. Check price on Amazon
Best inspection-friendly upgrade: Sylvania SilverStar Ultra. Whiter than stock while staying a DOT-marked halogen, which keeps things simple if your state checks vehicle lighting. About $25 to $40 a pair. Check price on Amazon
Read the code off the part you are pulling, then price it at AutoZone or O’Reilly for a same-day fix and at Amazon or RockAuto if you can wait. Buying headlights in matched pairs, sized to what your car actually uses, keeps the beam even. For the rest of the vehicle see our car parts guide, and for the household kind our light bulbs guide.
FAQ: Buying Headlights
How much does it cost to replace headlights?
Basic halogens run $15 to $30 a pair and conversion kits $40 to $120, while a complete factory unit starts near $150. The cheapest genuine improvement is usually a premium halogen pair plus a lens restoration.
Are LED conversion kits street legal?
An LED capsule installed in a housing certified for halogen is not a DOT-compliant configuration, because FMVSS 108 certifies the complete headlamp system rather than the source on its own. Enforcement varies: some states inspect vehicle lighting on a schedule, others run none at all, so check your own state’s program.
How do I find the right bulb code for my car?
Read the code molded into the base of the part you are removing, then cross-check the owner’s manual under lamp replacement. Year-make-model lookups at AutoZone, O’Reilly, and RockAuto confirm it. Low, high, and fog positions often use three different codes on the same car.
What are the three main types of headlights?
Halogen, HID/xenon, and LED, with sealed beam as the legacy fourth still fitted to pre-1990s vehicles. Halogen burns a filament in halogen gas, HID strikes an arc and needs a ballast, and diode emitters reach full output instantly. Most new US models ship with the third type as standard equipment.
Can I fix cloudy lenses instead of replacing the whole unit?
Usually, yes. Clouding is UV damage to the polycarbonate surface, so wet-sanding and polishing restores clarity for a fraction of the cost. Restoration kits sell for roughly $15 to $30 at the same parts chains. Skip the UV-blocking clear coat and the haze comes back within a year.
Why do newer cars look so much brighter to oncoming drivers?
Three things stack up: whiter light reads as harsher to the eye, trucks and SUVs mount their lamps higher, and a misaimed unit loses the sharp cutoff that keeps glare off other windshields. Aim is the part you control, and it takes minutes against a flat wall.
