CSL-Style LED Headlights — BMW 4 Series (F32/F33/F36) & M3/M4 (F80/F82/F83)
Full Bi-LED Conversion with Multi-Mode CSL DRL — Xenon & LED to 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 recognizable details in BMW's recent history — the laser-etched strip that turned the M4 CSL's face into something you could identify from three cars back. These headlights bring that signature to every F32-platform car, paired with a precision Bi-LED projector that replaces your factory xenon or LED optics entirely.
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 on the platform: pre-LCI xenon, pre-LCI adaptive xenon (AHL), pre-LCI LED, and LCI LED. Plug-and-play with zero coding.
Step 1 — Match Your 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 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
Four Connector Versions — One for Every Harness
The F32 platform shipped with four distinct headlight connectors: 6-pin (LCI LED), 8-pin (pre-LCI xenon), 9-pin (pre-LCI adaptive AHL xenon), and 10-pin (pre-LCI adaptive LED). We manufacture a dedicated version for each one — internal electronics pre-configured for your specific harness, CAN-bus behavior matched to factory expectations.
Ships Complete — Nothing to Transfer
Every assembly includes all LED drivers and control electronics pre-installed. No xenon ballasts to move, no D1S bulbs to source, no ignitors to carry over. This is a complete xenon-to-LED or LED-to-LED upgrade — your factory headlights stay intact.
Bi-LED Projectors with Auto-Leveling
A single Bi-LED module per side handles both low and high beam with a sharp cutoff line and wide, even coverage. Instant-on with no warm-up delay. The integrated auto-leveling motor adjusts beam height based on vehicle load. Auto high-beam assist continues to work exactly as it does with the factory headlights — no lost functionality, no warning lights.
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.
Yes. Auto high-beam assist functions identically to the factory headlights — the assemblies respond to the same CAN-bus signals your original units did, so the camera-based high/low switching keeps working without any reconfiguration.
Everything behind the lens. The xenon ballast, D1S bulb, and ignitor are all eliminated. You get a complete LED conversion — Bi-LED projector, CSL light-guide DRL, integrated leveling motor — in a housing that plugs directly into 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, projector module, DRL electronics, 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.
