CSL-Style LED Headlights — BMW 4 Series (F32/F33/F36) & M3/M4 (F80/F82/F83)
Complete Bi-LED Conversion with Multi-Mode CSL DRL — Xenon & LED to Full-LED Upgrade — Pre-LCI & LCI — 2013–2020
BMW F32 Coupe • F33 Convertible • F36 Gran Coupe • F80 M3 • F82/F83 M4 • Pre-LCI & LCI • 2013–2020
The CSL light guide is one of the most distinctive details in recent BMW history — the laser-etched lighting signature that makes the M4 CSL instantly recognizable, even from several cars away in the rear-view mirror. These headlights bring that unmistakable signature to every F32-platform model, paired with Bi-LED optics based on the BMW F32 LCI headlight layout, replacing your factory xenon or LED assemblies with a complete modern LED system.
Choose from four DRL configurations — from clean White to tri-color setups with Yellow, Amber, or Red. Every LED driver and control module comes pre-installed. We manufacture four connector-specific versions covering every factory harness used across the platform: pre-LCI xenon, pre-LCI adaptive xenon (AHL), pre-LCI LED, and LCI LED.
Each version connects directly to the matching factory harness — no adapters, no wiring modifications, and no coding required.
Step 1 — Choose the Correct Factory Connector

Step 2 — Choose Your DRL Configuration
White
The clean OEM look.
Fixed White DRL. The CSL light-guide shape in its purest form — understated, crisp, and factory-correct.
White + Yellow
The CSL signature.
Switch between crisp White and Selective Yellow (~3,000K) — the color that defined the M4 CSL's identity.
White + Yellow + Amber
Top spec — heritage warmth.
White, Yellow, and a deeper Amber — a warmer, richer take on the CSL yellow that leans into BMW's motorsport heritage while keeping the signature intact. Three modes, switchable from the cabin.
White + Yellow + Red
Top spec — full aggression.
White, Yellow, and a bold Red — the loudest face this platform can wear. The same three-mode switching logic as the Amber variant, but dialed to maximum presence when you want it.
DRL Color Switching
On multi-color variants, toggle between DRL colors using your high-beam lever. No apps, no Bluetooth module, no physical switch.
-
White + Yellow:
Flash high beams 5× to toggle between White and Yellow. -
White + Yellow + Amber:
4× → White • 5× → Yellow • 6× → Amber -
White + Yellow + Red:
4× → White • 5× → Yellow • 6× → Red
Engineered to Stay on the Car
Built for Your Factory Connector
Choose the version that matches your original 6-pin, 8-pin, 9-pin, or 10-pin connector. Each assembly is pre-configured for that exact harness and matched to the vehicle's CAN-bus behavior — plug directly into the factory connection with no adapters, no wiring modifications, no coding, and no warning lights.
Complete Assemblies — Nothing to Transfer
Every headlight includes its LED drivers and control electronics pre-installed. No xenon ballasts to move, no D1S bulbs to source, and no ignitors to carry over. This is a complete xenon-to-LED or LED-to-LED upgrade, while your original headlights remain fully intact.
Bi-LED Optics
A dedicated Bi-LED lighting unit on each side handles both low and high beam within an F32 LCI-inspired housing. It delivers broad, even road illumination with full output available instantly and none of the warm-up delay associated with xenon lighting.
Integrated Automatic Leveling
The built-in leveling motor automatically adjusts beam height as vehicle load changes, helping maintain a correctly positioned light pattern. Integrated manual adjusters are also provided for final beam alignment after installation.
Sealed Construction
ABS housings with PMMA lenses, sealed against moisture at every joint. Every pair is bench-tested before shipping.
QC'd Before It Leaves
Every pair is bench-tested for low beam, high beam, DRL, and leveling function before it ships. Two years of coverage from delivery date.
Installation
A straightforward headlight swap requiring front bumper removal — standard on the F32 platform. No wiring modifications, no coding on any version. Allow 2–3 hours.
- Remove the front bumper to access the headlight mounting bolts.
- Unbolt the factory headlights and disconnect the main harness plug.
- Plug the new headlight into your factory harness — the connector is specific to your pin count.
- Test before reassembly — verify low beam, high beam, DRL, and turn signals.
- Reinstall the bumper, align beam height using the integrated adjusters.
Frequently Asked Questions
Yes. The F80 M3 and F82/F83 M4 share the same headlight mounting points and harness as the standard F32/F33/F36. Select the connector version that matches your factory setup.
Yes. All F32-platform body styles share identical headlight geometry and connectors.
No. The 9-pin version is built specifically for the adaptive xenon harness. The physical AHL swiveling is replaced by a fixed, wide-angle Bi-LED beam pattern. No coding, no error codes.
Everything behind the lens. The xenon ballast, D1S bulb, and ignitor are all eliminated. You get a complete LED conversion — Bi-LED lighting, CSL light-guide DRL, and an integrated leveling motor — in a housing that connects directly to your existing harness. No adapters, no wiring work.
The factory LED headlights use the standard corona-ring DRL design. These assemblies replace it with the CSL light-guide signature and add multi-color DRL options — something the factory units don't offer.
Both are three-mode tri-color headlights with identical switching logic — the only difference is the third color. Amber is a deeper, warmer take on the CSL yellow with a heritage feel. Red is pure aggression — the boldest, loudest DRL this platform can wear. Pick the one that matches your build.
Count the pins on the main connector at the back of your current headlight. Alternatively, send us your VIN and we'll confirm your exact configuration in minutes.
Nothing. Every component is pre-installed — LED drivers, LED light modules, DRL electronics, and leveling motor. Your factory headlights stay fully intact.
Yes, if you're comfortable removing the front bumper on the F32 platform. Standard hand tools and about 2–3 hours. No lift required.
