BMW G20/G80, M340i/M3 CSL Taillights

BMW G20/G80 M340i/M3 CSL Taillights

Give the back of your BMW the look it should have come with. These CSL Style LED Taillights replace the factory units with the layered, multi-bar light signature of the CSL and GTS cars — the single most recognisable rear-end upgrade available for the G20 platform.

The factory taillight uses a comparatively plain L-shaped graphic. These replace it with a deeper, three-dimensional signature: stacked light blades that give the rear real presence at night and a far more purposeful look during the day.

These are complete assemblies, supplied as a matched left and right pair. Each is a full replacement unit with its own LED tail, brake and indicator functions — nothing is reused from your existing lights.

Full LED throughout, with a 6000K output, sharp illumination and the instant response LEDs give over the factory globes.

Key Features

CSL Style Light Signature

The layered multi-bar graphic of the CSL and GTS cars, replacing the flatter factory pattern.

Complete Assemblies

A full left and right pair — not covers, overlays or inserts.

Full LED Throughout

Tail, brake and indicator functions are all LED, with instant response and a long service life.

Dark Tinted Housing

A smoked lens that sits flush and disappears into dark paintwork when the lights are off.

Plug-In Replacement

Mounts in the factory locations using the original fixing points.

Brand New Units

Manufactured new — not refurbished or pre-owned.

Vehicle Fitment

BMW G20 3 Series Sedan (2019+)
BMW G28 3 Series (2019+)
BMW G80 M3 / M3 Competition (2021+)

Includes M340i and the wider 320i / 330i range sharing the same rear light aperture.

These suit the sedan body. They do not fit the G21 Touring, which uses a different rear light.

Please Note

Professional installation is recommended. Access to the taillight fixings requires trim removal inside the boot.

Coding may be required depending on your vehicle's original lighting specification. Please discuss this with your installer before booking.

Supplied as a matched left and right pair.
