CSL White/Yellow Switchable DRL Modules — BMW G20/G21 3 Series LCI (Laser)
Switchable White/Yellow DRL — Pre-Installed Heatsinks — Plug-and-Play — LCI Laser Headlight — 2023+
G20 Sedan • G21 Touring • LCI • Laser Headlight • 2023+
The G20 LCI sharpened everything — slimmer headlights, redesigned DRL graphics, and on Laser-equipped cars, those distinctive blue accents that instantly signal the premium option. These modules give you the one thing BMW left out: switchable CSL yellow. Toggled from the high-beam stalk in under two seconds, plus strobe, breathing, and an automatic mode tied to your low beams. White is calibrated to match your factory Laser DRL color temperature; the car looks factory-correct at a glance.
Fits LCI Laser headlights on 2023+ G20/G21 only. Does not fit pre-LCI (2019–2022) or LCI Adaptive LED without Laser. Available in separate EU-market and US-market versions — see below.
Step 1 — Is This Your Headlight?
These modules fit the LCI (2023+) Laser headlight on the G20/G21 only. The LCI Laser headlight has slimmer housings with redesigned L-shaped DRL graphics and blue accent strips around the DRL. If your car is a pre-LCI (2019–2022) or has the LCI Adaptive LED without blue accents, these modules are not compatible.

Slimmer LCI housing — L-shaped DRL with blue accents.
Step 2 — EU or US Market?
BMW uses different DRL electronics for EU-market and US-market LCI Laser headlights, so we ship two dedicated versions. Pick the one that matches the headlight in your car, not the country you're driving in.
How to know which you have
If your car was originally sold new in the EU, UK, or any right-hand-drive market, choose EU. If it was originally a US-market car — even if it's since been imported to Europe — choose US. The original-sale market sets the headlight electronics for the life of the car. Grey-import cars retain their original headlight hardware.
Not sure? The sticker on the headlight lens carries BMW's part number. Matching it to the list below confirms your version. You can also send us your VIN and we'll look it up in under an hour.

Complete modules, not bare boards.
Each Eleron module arrives as a finished assembly — LED board bonded to its own aluminum heatsink with thermal interface pre-applied. The install is clean mechanical work: unbolt, unplug, swap, bolt. Your factory modules come out untouched and stay factory-correct in a drawer, so the upgrade is fully reversible whenever you want. No separating boards from heatsinks, no thermal paste, no board-level work.
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 DRL. Your choice stays set until you change it.
-
5×Auto Mode Eleron Exclusive
Set it and forget the toggle. The DRL follows your low beams automatically: Yellow when low beams are off, White when they come on. Most competitor modules only offer manual toggling.
-
7×Strobe
A left-right progressive strobe in your current DRL color. Flash 7× again to switch the strobe to the other color. A show mode, not for road use.
-
11×Ambient Breathing
A slow, subtle pulse where the DRL dims in and out. Best used while parked or at idle — not intended for driving.
-
9×Reset
Returns the module to factory White DRL and clears all mode settings.
Built for LCI Laser
Plug-and-Play — Zero Coding
Built specifically for the LCI Laser DRL circuit. Connects to your factory controller and wiring — no coding, no CAN adapters, no error codes. Your BMW doesn't know anything changed.
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.
Fully Reversible
The LCI Laser headlight is a premium option that holds resale value. Factory modules come out intact and go in a drawer — bolt them back in for a lease return, sale, or dealer visit. Same process, same screws, no residue.
2-Year Warranty
Two years of coverage from delivery date on every set.
Installation
The LCI headlight design sits tighter in the front end than the pre-LCI. Reaching the DRL modules requires either removing the front wheels and fender liners or a partial bumper release to pull the headlight unit forward enough to access the rear. Plan for the bumper-release method if you want comfortable working room — it adds time but gives full access to both sides.
Once you have access: disconnect the factory DRL connector from the rear of the headlight, unbolt the OEM module, plug the Eleron module into the same connector, secure with the original screws. Test both White and Yellow DRL before closing everything up. Plan for a half-day if you're comfortable with trim work, or book a local shop — they'll quote 1–2 hours of labor.
Tools: T20 and T25 Torx bits, 8mm and 10mm sockets, trim removal tool, jack and stands if you're going the wheel/liner route.
Frequently Asked Questions
No. The DRL is a separate LED circuit from the laser-assisted main beam. These modules only replace the daytime-running LED board — your Laser high-beam system continues to function exactly as BMW designed it.
The LCI Laser headlight has blue accent strips around the DRL graphics — visible when the headlights are off. The LCI Adaptive LED without Laser lacks these blue accents. If you don't see blue, you have the non-Laser version, which needs a different product.
No. The pre-LCI headlight has a different DRL architecture and connector. We sell a dedicated pre-LCI Laserlight DRL module — check our G20 Pre-LCI Laserlight product page or message us.
No. The LCI Adaptive LED without Laser uses different DRL electronics. We make a separate product for that headlight — message us and we'll point you to it.
Yes. The G20 Sedan and G21 Touring share identical LCI Laser headlight housings and DRL modules.
Pick the market the car was originally sold in. If it was a US-market car that's now in Europe, order the US version — the headlight electronics don't change when the car is re-registered. The sticker on your headlight carries BMW's part number and confirms the market. If you're unsure, send us your VIN and we'll check it against the factory build sheet.
The LCI headlight sits tighter in the front end than the pre-LCI. Most owners find a partial bumper release or full bumper removal necessary to pull the headlight forward enough to access the DRL modules on the back. A shop will quote 1–2 hours of labor.
No. The modules draw the same current as the factory DRL and speak the same CAN signals to your headlight controller. No coding needed, no codes thrown.
BMW occasionally updates part numbers during a model's production run — the superseding number replaces the original in BMW's catalog, but both refer to the same physical module. Our product is compatible with either. Check the sticker on your headlight to see which number you have.
White matches the factory LCI Laser DRL color temperature, so the car looks stock at a glance — the right pick when you want the OEM aesthetic. Yellow is the CSL-style signature, the detail that sets M3/M4 CS models apart at shows and meets. Switching takes under two seconds from the driver's seat, so your configuration isn't locked in.
