CSL White/Yellow Switchable DRL Modules — BMW G22 4 Series, G80 M3, G82 M4 (Adaptive LED)
Switchable White/Yellow DRL — Pre-Installed Heatsinks — Plug-and-Play — Pre-LCI Adaptive LED — 2021–2024
G22 Coupe • G23 Convertible • G26 Gran Coupe • G80 M3 • G82 M4 • G83 M4 • i4 • Adaptive LED • Pre-LCI • 2021–2024
The G22 Adaptive LED headlight has one of the sharpest DRL signatures in BMW's current lineup — the angular light bar that gives the 4 Series and M4 their identity. These modules let you switch it to CSL yellow 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 DRL color temperature; the car looks stock at a glance.
Fits Adaptive LED headlights (non-Laser) on pre-LCI 2021–2024 G22/G23/G26, G80 M3, G82/G83 M4, and i4. Same module for EU and US markets — no market selection needed.
Is This Your Headlight?
These modules fit the Adaptive LED headlight — the standard factory LED on pre-LCI 2021–2024 G-chassis cars. No blue accents inside the housing, no "BMW Laser" script on the lens. If your headlights have blue "L" inlays and a thick horizontal DRL bar, you have Laserlight (option 5AZ) — which needs a different product. If your car is a 2024+ LCI with the redesigned arrow-shaped DRL, these are also not compatible.

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 Adaptive LED
Plug-and-Play — Zero Coding
Built specifically for the G22 Adaptive LED DRL circuit. Connects to your factory controller and wiring — no coding, no CAN adapters, no error codes. AFS beam swiveling, welcome light, selective beam, and turn signal integration all stay exactly as BMW engineered them.
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
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
Honest version: the G-chassis headlight design means the DRL modules aren't top-accessible from the engine bay. You have two paths to reach them. The cleaner method is to remove the front wheels and fender liners — this gives enough room to release the headlight mounting bolts and pull each unit forward a few centimeters to work on the back. The alternative is a full front bumper removal, which is more involved but gives you full working access.
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 interior trim work, or book a local shop if you'd rather not touch the bumper or fender liners yourself.
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
Laserlight (option 5AZ) has blue "L" accents visible inside the headlight housing, a noticeably thicker horizontal DRL bar, and often a "BMW Laser" script on the outer lens. Adaptive LED has no blue accents and no laser script — just the standard angular DRL bar. Each uses a different DRL connector, so you need to match the product to your headlight type.
No. Laserlight uses different DRL electronics and a different connector. We sell a dedicated Laserlight DRL module — check our G22 Laserlight product page or message us.
No. The LCI uses a redesigned headlight with a different DRL architecture. These modules are for the pre-LCI (2021–2024) only.
Yes. All G-chassis pre-LCI cars with Adaptive LED headlights use the same DRL module and connector — G22 Coupe, G23 Convertible, G26 Gran Coupe, G80 M3 Sedan, G82 M4 Coupe, G83 M4 Convertible, and the i4.
Yes. The DRL module is a completely separate circuit from the AFS beam-steering system. Selective beam, cornering logic, welcome light, turn signal integration — all preserved.
No. One module fits both EU and US market Adaptive LED headlights — no market selection needed.
Yes. The DRL modules on G-chassis cars sit behind the headlight housing, not on top of it. There's no engine-bay shortcut. The wheel-and-fender-liner route is cleanest; full bumper removal gives more working room. 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.
White matches the factory Adaptive LED 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 M4 CSL and CS models apart at shows and meets. Switching takes under two seconds from the driver's seat, so your configuration isn't locked in.
