Audi A4 / S4 Sedan B9 + B9.5 (2016-2024) Chrome Crystal Custom Taillights

Crystal Chrome Custom Taillights – A4/S4 Sedan B9 + B9.5 (2016-2024)

These Audi A4 clear tail lights are built for the A4 and S4 sedan across two generations: the B9 pre-facelift from 2016 to 2019, and the B9.5 facelift from 2019/2020 to 2024. Each set starts as a genuine used OEM core and is hand-rebuilt in our own workshop with a crystal-clear lens and bright chrome trim.

Most B9-era sedans on the road are aging at the back. Years of sun and heat cycles leave the factory lens faded and hazed, and a brand-new dealer panel costs serious money. This set solves the problem in one move: full lens clarity up front, crisp chrome trim around each housing, and a freshly resealed factory core behind it.

Built From Genuine OEM Cores, Not Aftermarket Shells

Each set of Audi A4 clear tail lights is built on a genuine used OEM core sourced from a real donor car, never a cheap ABS aftermarket shell. We fully open the housing, clean and inspect every internal component, replace worn seals, and rebuild the unit with professional-grade sealant before it ever leaves the bench.

Most mass-market A4 custom taillights are built on aftermarket shells that need trimming and fight the factory connector. Ours keeps the original lens profile, mounting points and connector layout exactly where Audi put them, so you get an OE-grade part with a custom look instead of a replica.

What goes into a set like this? Each pair takes hours of bench work: careful disassembly, lens polishing to optical clarity, chrome trim finishing, fresh seals throughout, and a full function test of every light before packing. Nothing is rushed and nothing is hidden behind tint.

The Crystal Chrome Look

The Audi A4 chrome tail lights in our Crystal Chrome style pair a fully clear outer lens with bright chrome trim, letting you see straight into the housing. The result is a clean, factory-plus rear end that reads custom without looking tacky. There is no film, no spray tint and no overlay to peel – the clarity is the actual lens itself.

Audi S4 clear tail lights should look like they came from the factory, not like tinted covers dropped on top. Because the housing is a genuine unit and the lens is optically clear, the chrome reflector surfaces stay bright and the whole rear end reads crisp in daylight and sharp at night.

Because the housing is a genuine factory unit, light output and beam pattern stay true to stock. The clear lens simply shows off the internal reflectors and light guides that Audi engineered, giving the sedan a crisp modern edge that tinted covers can never match.

Fixing the Fog – a Properly Resealed Housing

Tail light condensation is a well-known complaint on these sedans, and it is one of the main reasons owners end up replacing their Audi A4 clear tail lights. Moisture creeps past aged factory seals, fogs the lens from the inside and leaves water stains that never fully go away. Our rebuild process addresses the root cause: every housing is opened, dried and resealed with professional-grade sealant applied along the full seam, then checked before it ships.

This is the same class of fix the factory service bulletins describe for fogged units, done to a higher standard. You get a housing that stays clear through rain, car washes and temperature swings – not a temporary patch that fails again next winter.

Plug and Play – No Coding Required

These Audi A4 clear tail lights are plug and play. They connect directly to the factory harness with no cutting, splicing or dealer coding, and they work with the car’s original bulb monitoring, so no error messages appear on the dashboard after the swap.

Most owners complete the install with basic hand tools in an afternoon. Unbolt the old unit, transfer the connection, bolt the new set in place and you are done. If you have any questions about fitment, send us your VIN before ordering and we will confirm the correct version for your build.

Fitment and Version Guide

These Audi A4 clear tail lights cover both sedan generations: Audi A4 B9 tail lights for the 2016-2019 pre-facelift, and Audi A4 B9.5 tail lights for the 2019/2020-2024 facelift. Audi S4 B9.5 tail lights share the same housing as the facelift A4, so the set fits them too.

Because the B9 and B9.5 use different internal layouts and connectors, send us your VIN and a photo of your current lights before ordering and we will confirm the exact version for your build – it prevents a wrong-side or wrong-generation mix-up.

If anything looks different, message us before your set ships and we will double-check compatibility against your VIN.

Frequently Asked Questions

Will these fit both the B9 and B9.5 A4 / S4?

Yes – but each generation has its own housing, so we match the set to your car. The B9 pre-facelift runs 2016-2019, while the B9.5 facelift runs 2019/2020-2024, and the S4 follows the same split. The correct set is confirmed against your VIN before shipping.

That is why we ask for a quick photo of your current lights with the order. It lets us verify the connector and internal layout, so you receive the exact generation that plugs straight in.

Are they plug and play with no error codes?

Yes. The set connects to the factory harness through the original connectors, with no cutting, splicing or adapter work. The electronics communicate with the car exactly like the stock units, so the bulb monitoring system stays quiet – no bulb-out warnings or error codes on the dash.

No coding, no flashing and no dealer visit required. Bolt the set in, plug it in and drive.
