F30 3 Series CSL Yellow Headlight DRL Module Upgrade (2016 - 2018 LCI LED Only)

Upgrade the front-end lighting appearance of your BMW F30 3 Series with this CSL Yellow Headlight DRL Module Upgrade. Designed specifically for 2016-2018 BMW F30 LCI models equipped with factory LED headlights, this upgrade adds a bold motorsport-inspired yellow DRL signature while retaining the factory headlight assembly.

The CSL yellow DRL style delivers a more aggressive and performance-focused look, inspired by modern BMW M lighting accents. This module upgrade is ideal for owners who want to refresh their factory LED headlights without replacing the complete headlight assemblies.

Designed for compatible LCI LED headlight applications only, these DRL modules replace the factory daytime running light boards to create a clean yellow output. Professional installation is recommended to ensure proper headlight disassembly, module fitment, sealing, and long-term reliability.
