Dual Color Switching CSL Yellow / White DRL Upgrade - G80 M3 / G82 M4 / G22 4 Series

CSL yellow DRLs are a statement. White is the daily. This kit lets you run both — and switch between them without pulling a panel, opening an app, or touching a wire. Three flashes of the high beam stalk is all it takes. The module saves your last selection to memory, so the car wakes up exactly how you left it.

Under the hood it's a complete LED board swap for both housings — not a film, not a tint, not a wrap. Real CSL yellow output on dedicated boards, with OEM switchback turn signal behavior completely intact. Install is fully plug-and-play and reversible if you ever want to go back to stock.

Highlights:

• Toggle between CSL yellow and white DRLs via high beam stalk — three flashes switches modes
• Memory function holds your color selection through every restart
• Dynamic startup sequence on every ignition cycle
• Full LED board replacement for both left and right headlights — not a filter or overlay
• OEM switchback turn signal functionality completely retained
• True plug-and-play — no coding, no permanent modifications, fully reversible
• Thermal conductive adhesive tape included for proper board seating
• Complete installation instructions included in kit

Notes: No coding required. Fully reversible — stock boards can be reinstalled at any time. Verify headlight type before ordering
