This is a complete left and right pair of GTS and CS style full LED tail light assemblies built to replace the factory rear lamps on BMW 4 Series F32 Coupe, F36 Gran Coupe, F82 M4 Coupe, and F83 M4 Convertible models from 2014 to 2020. The kit replaces both the outer body and inner boot lid sections on both sides, delivering a dramatic visual upgrade with deep red lenses, sequential flowing LED turn signals, LED running lights, LED brake lights, LED fog signals, and LED reverse lights. Installation uses the factory wiring harness connectors with all necessary adapter loom cables included in the package. No splicing or permanent wiring modification is required.
IMPORTANT FITMENT NOTE: This product fits the F33 Cabrio in facelift specification from 2018 to 2020 only. It will NOT fit the pre-facelift F33 Cabrio built before 2018. Buyers who are unsure of their vehicle specification should contact the seller to confirm fitment before ordering.
Key Features and Benefits
Sequential flowing LED turn signals sweep outward in an animated wave pattern on both the outer and inner tail light sections, giving the vehicle a modern, high-end lighting signature that is visually distinct from the factory lamps at night and during the day.
Full LED construction across every light function. Running lights, brake lights, turn signals, fog signals, and reverse lights all use LED elements. There are no filament bulbs anywhere in this assembly.
The deep red smoked lens design replicates the GTS and CS competition styling, giving the rear of the vehicle a more aggressive and visually unified appearance compared to the lighter-tinted factory units.
High and low voltage protection circuitry is built into the assembly, protecting against electrical spikes and voltage fluctuations common in older F-chassis vehicles.
Reverse polarity protection prevents damage if the harness is connected incorrectly during installation.
Water and shock resistant construction. The housing features a rear heat sink design that prevents thermal buildup during extended use, extending the service life of the LED elements.
The professional-grade ABS and PMMA housing construction resists UV degradation, impact, and temperature variation, maintaining optical clarity and structural integrity over years of daily use.
Dedicated adapter wiring harnesses for all four lamp positions are included in the package. No wiring modification to the vehicle is required.
LED brake lighting provides faster illumination response time compared to incandescent bulbs, reducing rear collision risk.

Installation Notes and Special Functions
This is a complete plug and play assembly. The included wiring adapter looms connect directly between the factory harness connectors in the boot and the new lamp units. No permanent wiring changes are required.
The sequential turn signal function operates automatically through the adapter loom without additional controllers or modules.
The flowing LED running light animation is active whenever the vehicle lights are switched on, giving the rear a distinctive lit appearance even when stationary.
Professional installation is strongly recommended. Incorrect handling of the tail light housing or wiring connectors can result in water ingress, electrical faults, or damage to the vehicle body loom. An auto electrician or experienced workshop should perform the installation if the buyer is not confident working with automotive lighting and wiring.
No installation instructions are included with the product. Buyers should source a fitment guide or video for their specific model before beginning installation.
If uncertain whether this product fits your exact vehicle, contact the seller with your chassis code, production month, and year before ordering.
