Tail Lights Compared: OE Replacements and LED Upgrades
The TYC 11-6236-00 replacement assembly is our top pick because fitment and sealing matter more than anything on a tail light. The Dorman 1611268 is the value alternative for older vehicles, and the Truck-Lite 60 Series LED lamp is the durable choice for trucks and trailers.
The TYC 11-6236-00 replacement assembly leads this roundup because with tail lights the important qualities are unglamorous, namely that the housing lines up with the body, the lens seals against water and the connector matches without splicing. The Dorman 1611268 covers the same ground for less on older vehicles, and the Truck-Lite 60 Series LED lamp is what to fit on a truck or trailer where vibration and weather destroy ordinary lamps.
Tail lights are one of the few parts where a cheap purchase shows itself within months, because a housing that seals badly fills with condensation, corrodes the contacts and fails again. Style upgrades add another variable, since many aftermarket LED assemblies look impressive in listings but carry no certification marking, which can fail an inspection. We compared fitment accuracy, sealing, output, certification markings and connector compatibility, using published specifications alongside what owners report about condensation and premature failure.
What matters most
Fitment is the whole job Tail light assemblies are body parts as much as electrical ones, and a housing that sits a few millimetres out leaves a gap that collects water and looks wrong. Manufacturers frequently use different assemblies across a single model year depending on trim and market, so verify by part number rather than by model name. Photographing your existing unit and its connector before removal makes it far easier to confirm you have the right replacement.
Sealing matters more than brightness Condensation inside a lens is the classic sign of a poor assembly, and it does more than look bad, since moisture corrodes contacts and shortens bulb life until the lamp fails again. Check that the replacement comes with a proper gasket, that the lens is bonded rather than merely clipped, and that the bulb sockets seal. When refitting, make sure any drain holes at the bottom of the housing are clear.
LED upgrades and certification LEDs light faster than filament bulbs, which gives following drivers a fraction more warning under braking, and they draw less current. The complication is legality. Many aftermarket LED assemblies and bulbs are sold without the certification markings required for road use, and some vehicles will report a bulb fault because the LED draws too little current for the monitoring circuit. Check for the markings your local inspection requires and budget for load resistors if needed.
Get the grounds right Most tail light faults that look like a failed lamp are actually a bad ground. Corroded ground points behind the panel cause dim lights, lights that glow when another circuit is active, and intermittent faults that come and go with vibration. Before replacing an assembly, clean the ground connection to bare metal and refit it properly. On trailers this is even more important, since many rely on the coupling for a ground path.
Our top picks
TYC 11-6236-00 Replacement Tail Light Assembly
TYC supplies replacement lighting to the collision repair trade, which means the housings are built to line up with body panels and the lenses carry the certification markings inspectors look for. Sealing is the important part and this is where the branded assemblies pull away from anonymous listings. It costs more than the cheapest options, and you must confirm the exact part number against your vehicle since one model year often uses several variants.
Pros
- Panel gaps line up like the original
- Certification marking satisfies inspections
- Seals properly so condensation stays out
Cons
- Costs more than unbranded assemblies
- Exact part number must be verified by variant
Dorman 1611268 Tail Light Assembly
Dorman specialises in replacement parts for vehicles past their warranty, so the catalogue covers older models that other suppliers have dropped. The assemblies are straightforward direct fit units with the correct sockets and mounting points. Finish is a step below the collision trade brands, with slightly softer lens clarity, which matters less on an older vehicle than on a nearly new one.
Pros
- Covers older vehicles other brands have dropped
- Direct fit with original mounting points
- Sensible outlay for a car past warranty
Cons
- Lens clarity slightly below trade brands
- Bulbs usually sold separately
Truck-Lite 60 Series LED Stop Turn Tail Lamp
Truck-Lite builds commercial vehicle lighting where lamps live in road spray, salt and constant vibration, and the 60 Series is the round sealed LED lamp you see on working trucks and trailers. The potted construction has nothing inside to corrode, which is why these outlast several sets of conventional lamps. It is a round commercial lamp rather than a styled car assembly, so it suits utility applications not passenger car upgrades.
Pros
- Sealed construction resists water and salt
- Survives vibration that kills bulb lamps
- Instant LED illumination for stop lights
Cons
- Utility styling not suited to passenger cars
- Grommet and pigtail may be a separate purchase
ANZO USA LED Tail Light Assembly
ANZO is one of the longer established names in styled aftermarket lighting, offering LED assemblies with smoked or clear lenses for popular trucks and cars. The visual change is significant and LED illumination lights faster than a filament bulb, which is a small genuine safety benefit. Check the specific listing for certification markings and confirm whether your vehicle needs a resistor to avoid bulb out warnings.
Pros
- Noticeable styling change over the original
- LEDs illuminate faster than filament bulbs
- Established brand with vehicle specific fitments
Cons
- Certification varies by listing so must be checked
- May trigger bulb out warnings without resistors
DEPO Replacement Tail Light Assembly
DEPO assemblies turn up constantly in insurance repairs because they cover an enormous range of vehicles at a lower cost than trade brands. Fitment is generally sound, and for a car that needs a lens replaced to pass an inspection they do the job. Quality varies more between individual units than with premium brands, so inspect the gasket and lens seal before fitting.
Pros
- Covers a very wide range of vehicles
- Common choice for insurance repairs
- Lower outlay than trade brands
Cons
- Unit to unit quality varies
- Seal should be inspected before fitting
Optronics ONE Series LED Combination Tail Light
Optronics designs these for trailers including boat trailers, so the housings are sealed against submersion which is exactly what a launch ramp does to ordinary lamps. The combination unit handles stop, turn, tail and licence plate illumination in one housing to simplify wiring. It is trailer specific, so it has no application on a passenger vehicle.
Pros
- Handles submersion at boat ramps
- Combines several functions in one housing
- LED draw is low for older trailer wiring
Cons
- Trailer application only
- Requires a good ground to work reliably
Blazer International C6423 Trailer Tail Light Kit
This is a full kit with both lamps, the wiring harness and the fittings needed to light a small trailer from scratch, which saves assembling parts individually. For a utility or boat trailer with corroded wiring, replacing everything at once is usually quicker than tracing faults. The included harness is basic, so anyone building a trailer for heavy use may want to upgrade the wiring separately.
Pros
- Everything needed in one purchase
- Faster than tracing corroded trailer wiring
- Sensible outlay for a complete rewire
Cons
- Included harness is basic
- Not intended for heavy commercial use

Common questions
How do I know which tail light assembly fits my car?
Match by year, model, trim and body style, and verify the part number rather than trusting the listing title. Photograph the existing unit and connector before removal. Many models use two or three different assemblies within the same year depending on trim or market.
Are aftermarket tail lights legal?
It depends on certification. Assemblies carrying the marking required in your region are legal for road use, while unmarked show parts often are not and can fail an inspection. Check the specific listing rather than assuming, since brands sell both certified and off road only versions.
Why does my tail light have condensation inside?
Either a failed seal, a cracked lens, a poorly seated bulb socket, or blocked drain holes. Small amounts of misting that clear when the lights warm up are normal on some designs. Persistent standing water means the housing has failed and should be replaced.
Can I replace just the bulb instead of the assembly?
Yes if the housing and lens are intact. Replace bulbs in pairs so both sides match in brightness and neither fails soon after. If the lens is cracked or the housing is full of moisture, a bulb change only postpones the problem.
Do LED tail lights need load resistors?
On vehicles that monitor bulb current, often yes, otherwise the dashboard reports a bulb failure or the indicators flash rapidly. Some LED assemblies include built in resistance and say so. Check the product notes for your specific vehicle before fitting.
How long do LED tail lights last?
Typically far longer than filament bulbs, often many years of normal use, since there is no filament to break under vibration. Sealed commercial lamps last longest because there is nothing inside to corrode. Failures usually come from moisture ingress or wiring faults rather than the LEDs themselves.
Why do my trailer lights work intermittently?
Almost always a ground or connector problem rather than the lamps. Trailer grounds corrode quickly, and many trailers rely on the hitch for a ground path. Run a dedicated ground wire to each lamp, clean the plug contacts and apply dielectric grease to keep water out.
Should I replace both tail lights at once?
Not necessarily for a single collision damaged unit, though matching matters. A new lens next to a sun faded one is visibly different, and on older vehicles the second side often fails soon after. If both lenses are hazed, replacing the pair gives a consistent result.
Our pick
For a passenger car the TYC 11-6236-00 is the safest purchase because trade grade assemblies fit the body properly and seal against water, which is what actually determines how long a tail light lasts. On an older vehicle the Dorman 1611268 covers the same job for less. For trucks and trailers, fit the Truck-Lite 60 Series LED lamp and stop replacing lamps every couple of seasons.
