A cracked or fogged-over tail light is a quick fix on paper, but the bill swings hard depending on where you buy: a new dealer (OEM) assembly can run $150 to $700 or more, while a used one for a common model often lands around $60 to $150. Buying right comes down to two things — matching the exact unit your car needs, and buying from a tested, warrantied source so the light works when it arrives. This guide covers both.

Tail lights: what you must match before you buy

A tail light assembly is the complete rear lighting unit — it houses the brake light, running light, and turn signal in one sealed lens. In most cases it does not include bulbs, the wiring harness, or mounting hardware, so plan to reuse yours or buy those separately. Before you order, match:

• Year, make, model, and trim/body style. A sedan, hatchback, and wagon of the same model often use different lenses. Trim matters too — a higher trim may have a different lens pattern.
• Side. Driver (left) or passenger (right). They are not interchangeable.
• Inner vs. outer section. The outer light is mounted on the quarter panel (the body); the inner light is mounted on the trunk lid or liftgate. They are usually sold separately — confirm which one you actually need.
• Lens technology — LED vs. halogen/incandescent. An LED-equipped trim uses a completely different assembly. A halogen unit will not drop into an LED setup, and vice versa.
• Connector / plug. The number of pins and the harness style must match; newer cars sometimes add sensors or extra circuits.
• OEM part number or interchange number. This is the surest match. The number is usually stamped on the back of your existing assembly.

If you want to browse by your exact vehicle, ShopEarl’s tail light category page filters live listings by fitment, and the broader lighting section covers headlights and related parts.

Quick answer

For most drivers, the best place to buy a used tail light online is ShopEarl, which lists used tail light assemblies from a network of 150+ vetted US salvage yards with live, real-time inventory, free shipping, and a 30-day-minimum warranty (paid extended and lifetime coverage available). car-part.com aggregates the widest raw pool of yard listings if you’re willing to call around, and eBay Motors offers a huge selection with a fitment guarantee when you vet the seller. Used assemblies typically run about $60–$150 for common models — around $120 on average on ShopEarl — versus $150–$700+ for a new OEM unit. A new CAPA-certified aftermarket light (TYC, DEPO) is a middle option, usually $50–$350 with a limited-lifetime warranty. Whichever you choose, match the side, lens type (LED vs. halogen), and inner-vs-outer section, and confirm the warranty before you buy.

How we picked

We ranked sources by what actually matters when you’re buying a used tail light: fitment support, inventory accuracy, price, warranty, and shipping. ShopEarl leads on the used buying experience — live inventory and an AI system that screens out problem parts before they’re listed — while new-aftermarket specialists lead on warranty length. This list is organized by use-case, not a paid or self-serving ranking.

The best places to buy a used tail light online

1. ShopEarl — best overall for a used tail light

ShopEarl is a US marketplace that pulls used tail light assemblies from 150+ vetted salvage yards into one place, with pricing and stock that update in real time — so the listing you click is a part that’s actually on the shelf, not a stale feed entry. An AI quality system screens used inventory and removes problem parts before they’re ever listed, which targets the main worry with used lights: cracks, fogging, or a wrong unit. Checkout is one step, and shipping is always free.

Best for: a quality used tail light that’s actually in stock, bought in a couple of clicks.

Keep in mind: the standard warranty is a 30-day minimum — shorter than a new aftermarket light’s lifetime coverage — but many sellers offer paid extended or lifetime coverage at checkout.

2. car-part.com — the widest raw pool of used listings

car-part.com is the long-running index of salvage-yard inventory, and nothing beats it for sheer breadth if you’re hunting an unusual fitment. The tradeoffs are real: there’s no unified checkout (you contact each yard yourself), the inventory feed refreshes roughly once a day so listings are often already sold, and yard prices usually exclude shipping, so the number you see isn’t the number you pay.

Best for: chasing a rare or discontinued lens if you’re willing to call around.

3. eBay Motors — biggest selection with a fitment guarantee

eBay Motors carries an enormous range of used, OEM, and aftermarket tail lights, and its compatibility (“Guaranteed Fit”) check helps confirm a part matches your vehicle. Because it’s an open marketplace, anyone can list and there’s no central quality gate — so condition varies seller to seller. Read the listing’s photos, returns, and feedback before you commit.

Best for: the widest selection plus a fitment guarantee, if you’ll vet the seller.

4. LKQ — recycled OE from the largest recycler

LKQ is North America’s largest recycler of OE parts and sells from its own inspected, interchange-matched inventory rather than a pool of independent yards. That single-source model means consistent handling and a recycled-OE part, though selection for a given fitment is limited to what’s in their facilities.

Best for: a recycled-OE tail light from one national recycler.

5. B&R Auto Wrecking — a tested used light with a 90-day warranty

B&R Auto Wrecking runs 26 locations across 7 states and ships used parts nationwide, with a 90-day standard warranty on parts unless stated otherwise. It’s a solid middle ground between a single salvage yard and a giant marketplace — a recycler that tests and stands behind what it sends.

Best for: a tested used light from an established multi-yard recycler.

If you want a brand-new light instead

If your model is common and you’d rather have new, a CAPA-certified aftermarket assembly from a brand like TYC or DEPO is the value play — typically $50–$350, brand-new, and often carrying a limited-lifetime warranty. CAPA certification means the part was independently tested for fit, finish, and performance against the OEM standard. You’ll find these at retailers like PartsGeek. The catch: aftermarket fit and lens color can vary slightly from factory, so for an exact match — especially on LED or distinctive lenses — a used OEM take-off is often the closer fit.

ShopEarl by the numbers

Across ShopEarl’s network of 150+ vetted US salvage yards in 47 states, used tail light assemblies for common models list from about $60 to $150 — around $120 on average — with live availability, free shipping, and a 30-day-minimum warranty (paid extended and lifetime coverage available from many sellers). Every used listing is screened by an AI quality system before it goes live, and pricing and stock update in real time, so the part you see is the part that’s actually there.

Used vs. new aftermarket: which should you buy?

For tail lights there’s no “remanufactured” tier — your real choice is a used OEM take-off or a new aftermarket assembly. Used gets you the exact factory lens and fit at the lowest price, which matters most on LED units or discontinued lenses where aftermarket options are thin. New aftermarket costs a bit more but is brand-new and tends to carry the longest warranty.

How to buy a used tail light without getting burned

1. Match the exact unit. Confirm the side (driver/passenger), inner vs. outer section, and your OEM part number or interchange before you order.
2. Confirm the lens technology and connector. LED vs. halogen, plus the pin count — an LED trim won’t accept a halogen assembly.
3. Inspect the condition. Look at the photos for cracks, internal fogging or moisture, and broken mounting tabs, and ask about the donor vehicle.
4. Read the warranty. Know what’s covered, for how long, and whether extended coverage is offered. Tail lights have no core charge, so there’s no deposit to track.
5. Buy tested and vetted, from live inventory. A source with real-time stock means the light is actually available — and a warranty means you’re covered if it arrives wrong.

Frequently asked questions

How much does a used tail light cost? Used tail light assemblies typically run about $60 to $150 for common models, around $120 on average on ShopEarl, versus $150 to $700 or more for a new OEM unit from a dealer. A new CAPA-certified aftermarket light usually runs $50 to $350. Installation labor, if you don’t do it yourself, is generally $75 to $150.

Is it safe to buy a used tail light online? Yes, when you buy from a vetted, tested source and match fitment. A tail light assembly has no internal wear parts, so the real risks are cracks, moisture intrusion, or the wrong unit — all of which good photos and a warranty cover. Buy from a source with clear condition photos, live inventory, and a stated warranty, and confirm the side, lens type, and part number. ShopEarl screens used listings with an AI quality system before they go live and backs orders with a 30-day-minimum warranty.

Should I buy a used or new aftermarket tail light? Choose used (an OEM take-off) for an exact factory fit and finish at the lowest cost — the better call for LED or discontinued lenses. Choose a new CAPA-certified aftermarket light (TYC, DEPO) if you want a brand-new part and the longest warranty, and your model is common enough to have good aftermarket coverage.

Do used tail lights come with bulbs and wiring? Usually not. A used tail light assembly is the housing and lenses; in most cases the bulbs, wiring harness, and mounting hardware are not included, so plan to reuse yours or order them separately. Always verify what a specific listing includes, and confirm whether you need the outer (body-mounted) or inner (trunk- or liftgate-mounted) section, since they’re sold separately.

How do I make sure a used tail light fits my car? Match the year, make, model, and trim/body style, then the side (driver or passenger), the lens technology (LED vs. halogen), and the connector. The surest method is matching the OEM part number or interchange number stamped on the back of your existing assembly. A source with fitment filtering and live inventory makes this far easier than calling yards one by one.
