Switchable White / Yellow DRL Modules — BMW X3 G01 / X4 G02 & X3 M / X4 M Pre-LCI (Icon Adaptive LED)
The CSL Yellow Signature on Your Factory Adaptive LED Headlights — Bolt-In Module Set — No Coding, Fully Reversible — 2017–2021
BMW X3 G01 • X4 G02 • X3 M F97 • X4 M F98 • Competition • M40i • Pre-LCI (2017–2021) • Icon Adaptive LED (S552A) • OEM Ref 63117466107 / 108
The yellow DRL isn't just for the coupes. On an X3 or X4 — a tall, wide front end with the angular Icon DRL rings — the CSL-style yellow reads even more deliberate, the signature people associate with motorsport specials. This set puts it inside the Adaptive LED headlights your car already has: the ELERON modules bolt onto the factory mounting points, an inline control box handles the switching from your high-beam stalk, and nothing is cut, coded, or permanent.
One set covers both headlights and fits the whole pre-facelift family, which shares these headlights: BMW X3 (G01, from 2017), X4 (G02, from 2018), and the X3 M (F97) and X4 M (F98, from 2019, incl. Competition) — all up to the 2021 facelift, with the Icon Adaptive LED headlights (option S552A). It's the same coverage as BMW's own DRL modules, OEM references 63117466107 (left) and 63117466108 (right), identical for EU and US cars. And because the ELERON modules replace the factory ones outright, they're also the fix if one of your original DRL modules has already failed.

Is This Your Headlight?
This set is built for the Icon Adaptive LED headlights (option S552A), which the pre-facelift X3, X4, X3 M and X4 M all share — the adaptive units whose beams swivel with steering. The standard non-adaptive LED headlights use a different DRL module and aren't compatible with this set.
X3 / X4 Icon Adaptive LED (S552A)
G01 · G02 · F97 · F98 — pre-LCI · beams swivel with steering.
Not compatible: standard (non-adaptive) LED headlights, and the facelifted (LCI) X3/X4 from 2021 — both use different DRL modules.

How It Works
Your factory DRL is driven by two LED modules bolted inside the headlights. This set replaces them with ELERON dual-color units — finished assemblies, LED board bonded to its own aluminum heatsink — on the exact same mounting points, using the original screws. A compact control box then sits inline in the headlight harness: the car-side connector plugs into the box, the box plugs into the headlight, factory male/female connectors on both ends. Nothing is cut, nothing is spliced.
The modules draw the same current and speak the same signals as the factory DRL, so the car sees nothing unusual: no dashboard warnings, no flicker, and the welcome-light sequence plays exactly as before.
Why the inline box existsThe stalk-switching logic has to live somewhere, and putting it inside the headlight would mean baking the housing open. The inline box is what keeps this a bolt-and-plug install — it's the part that reads your high-beam stalk and tells the modules which color to run. Stick it anywhere convenient in the engine bay with the supplied tape, away from direct exhaust-manifold heat. (Our complete headlight units carry this logic built in — no box needed there.)
Five modes · One stalk · No app
DRL Control
Every mode switches from your factory high-beam stalk with low beams off. Your selection persists through ignition cycles.
-
3×Manual Toggle
Switches between solid White and solid Yellow. Stays set until you change it — through ignition cycles too.
White ~6,000K⇄Yellow ~3,000K CSL -
5×Auto Mode Eleron Exclusive
The DRL follows your low beams — set it once and never touch the toggle again. The same day/night behavior logic as the OEM CSL cars.
Beams off → YellowBeams on → White -
7×Strobe
A left-right progressive strobe in your current color; flash 7× again to strobe the other color. Strictly for a parked car on private ground — flashing forward lights are illegal on public roads in most countries.
Show mode · private ground only -
11×Ambient Breathing
A slow, subtle pulse — the DRL dims in and out. Best at idle or parked at a meet.
dim … bright … dim -
9×Reset
Returns the module to factory White and clears all mode settings — your undo button.

Engineered to Stay on the Car
Zero Coding, Zero Errors
The modules draw the same current and speak the same signals as the factory DRL, so the car's diagnostics stay clean — no coding, no dashboard warnings, no flicker. The welcome-light sequence is preserved. Plug in, bolt down, done.
Fully Reversible — OEM Stays OEM
Your factory modules come out intact, and the harness is never cut or spliced — the inline box uses factory connectors on both sides. Bolt the originals back in for a lease return, a sale, or a dealer visit: same screws, no residue, no trace.
The CSL Yellow — On Factory Headlights
The switchable yellow DRL signature usually means buying complete aftermarket headlights. This set delivers it inside the Icon Adaptive LED headlights your car came with — run the clean factory white day to day, flick to yellow when the occasion suits.
Bolt-In on Factory Mounting Points
The ELERON modules mount exactly where the originals sit, secured with the original screws. No adapters, no drilling, no glue — a like-for-like mechanical fit, matching OEM modules 63117466107/108.
Matched Pairs — Binned Together
Left and right modules are color-matched at QC before they ship, so your DRLs read identical side-to-side. Cheap imports often mix LED bins — one headlight slightly warmer than the other — and once you've noticed the difference, you can't un-notice it.
Factory Functions Untouched
The DRL is its own circuit. Adaptive beam swiveling, high-beam assistant, and the welcome-light sequences all keep working exactly as BMW designed — the modules and box never touch those systems.
2-Year Warranty
Two years of coverage from delivery date.
Installation
A bolt-and-plug job with basic hand tools (T20/T25 Torx, 8/10 mm sockets, trim tool). Typical time: 1.5–2 hours for both sides. A shop will quote 1–2 hours of labor.
- Gain access to the back of each headlight. On the G01, the cleanest route is removing the front wheel and fender liner on each side; taking the front bumper off gives the most working room.
- Disconnect the factory DRL connector and unbolt the OEM module.
- Bolt the ELERON module in its place using the original screws — same mounting points.
- Seat the control box inline in the headlight harness: the car-side connector plugs into the box, and the box plugs into the headlight. Factory connectors on both sides — nothing is cut or spliced.
- Mount the box anywhere convenient in the engine bay with the supplied double-sided tape, away from direct exhaust-manifold heat.
- Test before closing up — verify the 3× White/Yellow toggle and the 5× Auto mode, plus the welcome light.
- Refit the liner (or bumper) and wheel.
Frequently Asked Questions
Yes — that's exactly what this set is. The ELERON modules replace the factory DRL modules inside your existing Icon Adaptive LED headlights, giving you a switchable White/Yellow signature with no headlight swap, no coding, and no cut wiring.
The whole pre-facelift family, which shares these headlights: BMW X3 (G01, from 2017), X4 (G02, from 2018), and the X3 M (F97) and X4 M (F98, from 2019, incl. Competition) — all up to the 2021 facelift, with the Icon Adaptive LED headlights (option S552A). One set covers both headlights, and the same set fits EU and US cars. It does not fit the standard non-adaptive LED headlights or the facelifted (LCI) X3/X4.
Yes. The X4, X3 M and X4 M share the pre-LCI X3's Adaptive LED headlights and DRL modules — same parts, same set, same install.
Adaptive beams swivel with the steering at night — if yours track the wheel, you have them. The definitive check is option code S552A on your vehicle order: send us your VIN and we'll confirm in minutes.
No — the standard LED headlights use a different DRL module that this set doesn't replace. Send us your VIN and we'll point you to the right product for your headlights.
Yes — a different one. The LCI headlights use their own DRL modules; see our X3/X4 LCI White/Yellow DRL module set, which also covers the Laserlight headlights.
If the fault is a failed DRL module — the usual cause when a ring goes dark and the dash shows a daytime-running-light warning — then yes. These replace the factory modules outright, so a dead OEM module leaves the car with the fault gone and the White/Yellow switching gained. If you suspect wiring damage rather than the module, send us your VIN and symptoms first.
No. The modules draw the same current and speak the same signals as the factory DRL, so there are no dashboard warnings and nothing to code. The welcome light works as before.
Yes. The DRL is a separate circuit — adaptive swiveling, high-beam assistant, and the welcome-light sequences all continue working exactly as BMW designed.
Fully reversible. Your factory modules come out intact and the harness is never cut — the inline box uses factory connectors on both sides. Bolt the OEM modules back in with the same screws and the car is exactly as it left the factory.
From the driver's seat, with low beams off: flash the high beams 3 times to toggle between White and Yellow. Five modes total — 5× activates Auto, 7× Strobe, 11× Ambient Breathing, and 9× resets to factory White. Your selection is remembered through ignition cycles.
An ELERON exclusive: flash 5× and the DRL follows your low beams from then on — Yellow when the beams are off, White when they come on. It's the same day/night behavior logic as the OEM CSL cars, and it means you never touch the toggle again.
Yes, if you're comfortable removing a wheel and fender liner. Basic hand tools, 1.5–2 hours for both sides, no lift required. A shop will quote 1–2 hours of labor.
It replaces them. Those are BMW's own DRL modules for these headlights — fixed white units. The ELERON set mounts on the same points with the same screws and adds the switchable White/Yellow function the OEM parts don't have.
