CSL Laser-Style LED Tail Lights — BMW 1 Series (F20/F21) LCI
Laser-Etched Filament Design with Amber Indicators & Startup Animation — EU & US Fitment — LCI 2015–2019
BMW F20 5-Door • F21 3-Door • All Engine Variants • LCI • 2015–2019 • EU & US Market
The CSL laser filament is the detail that made people stare at the back of an M4 CSL in traffic. Ultra-thin intersecting light threads, etched with a precision that makes the tail light look like it costs more than it should. These tail lights bring that exact design language to the F20 — the same visual density and craftsmanship, scaled to the 1 Series housing.
High-intensity amber turn signals provide a crisp, modern signal when lane changing or turning. A startup animation plays when you unlock the car. Both the outer (fender) and inner (trunk lid) units are included — the full set. Plug-and-play on both EU and US market vehicles — select your market at checkout — with zero coding.
E-Marked (ECE) — road-legal. Amber indicators are compliant in both EU and US markets.
Step 1 — Select Your Market
BMW uses different tail light wiring harnesses for EU and US market vehicles. Select the market your car was originally built for — not where it's currently registered.
EU Market
Your car was manufactured and originally sold for the European market.
US Market
Your car was originally built for the US market — even if it's now registered in Europe.
Not sure? Send us your VIN and we'll confirm.
Step 2 — Choose Your Housing
Two finishes. Same laser filament architecture, same amber indicators, same startup animation.
Red
Heritage presence.
Classic red housing that reads factory-correct by day. At night, the laser filaments glow through the lens with an intricacy the standard tail lights can't approach.
Smoked
Darkened drama.
Smoked housing that subdues the daytime appearance and lets the laser filaments define the tail light entirely when lit. Maximum contrast.

Engineered to Stay on the Car
EU & US Market — Zero Coding
We manufacture dedicated versions for both European and US market F20/F21 LCI vehicles — select your market at checkout based on where your car was originally built. Both versions are plug-and-play with zero coding. If you're running a US-spec car in Europe and want clean amber indicators, these are a direct solution.
Amber LED Indicators
High-output amber LEDs provide a crisp, instant-on signal that replaces the factory's standard pattern with a vibrant, modern look. Fully compliant with road regulations in both EU and US markets.
CSL Laser Filament Architecture
Ultra-thin intersecting light threads etched into the light guide — the same visual language BMW uses on its CSL and motorsport-derived models. Visible at depth through the lens, creating a complexity that flat LED strips can't replicate.
Complete Set — Outer & Inner
Both the outer fender-mounted units and the inner trunk lid units are included. Full replacement — no mismatched lights, no partial upgrade. Four pieces total.
E-Marked (ECE)
Every unit carries ECE certification. Road-legal for TÜV, MOT, EU periodic inspections, and US state inspections.
2-Year Warranty
ABS housings with sealed construction, bench-tested before shipping. Two years of coverage from delivery date.
Startup Animation
When you unlock the car, a signature LED sequence plays through the laser filaments — a welcome effect built into the tail light's own logic board. No extra modules, no wiring. During normal operation, the tail lights function as standard brake, running, and indicator lights.
Installation
A straightforward tail light swap. No bumper removal, no wiring modifications, no coding. Allow 30–45 minutes.
- Open the trunk and remove the inner trim panels to access the tail light hardware.
- Unbolt the outer (fender) tail lights and disconnect the harness plugs.
- Unbolt the inner (trunk lid) tail lights and disconnect.
- Plug the new CSL laser-style units into your factory harness and mount.
- Test before reassembly — trigger the unlock sequence, then verify brake lights, running lights, reverse lights, and amber indicators.
- Reinstall the trunk trim panels.
Frequently Asked Questions
Yes. The F20 (5-door) and F21 (3-door) share identical tail light mounting points and connectors.
Select US Market. The wiring harness matches your car's original build market, not where it's currently registered. The amber indicators will work correctly on both EU and US harnesses.
Yes. Both Red and Smoked carry E-Mark (ECE) certification. The smoked treatment does not reduce light output below the legally required threshold.
Yes. You receive both the outer fender-mounted units and the inner trunk lid units — the complete set, left and right. Four pieces total.
We offer two tail light styles for the F20 LCI. The GTS-Style features a layered 3D filament design with three housing options (Red, Smoked, Smoked Red). The CSL Laser-Style features the ultra-thin intersecting filament pattern from BMW's CSL models, available in Red or Smoked. Both share amber indicators, startup animation, and the same plug-and-play fitment.
No. Both the EU and US versions are fully plug-and-play. Just select the correct market at checkout and the internal electronics handle the rest.
No. This tail light is designed for LCI (2015–2019) cars only. The Pre-LCI uses a different housing shape and mounting.
Yes. Tail light replacement on the F20 requires only basic hand tools and access to the trunk interior. No bumper removal, no lift. About 30–45 minutes.
