BMW G80 M3, M4 & 4 Series CSL Yellow DRL Module

Get the original CSL yellow daytime running light signature that started it all, straight from the legendary G82 M4 CSL. This DRL module replaces your factory white DRLs with a bold, motorsport-inspired yellow that transforms the front of your BMW M3, M4, or 4 Series. Plug and play, professionally fitted at our East London workshop.

The Original CSL Yellow Look

The G82 M4 CSL made the yellow DRL an icon, and it remains the most iconic BMW lighting upgrade there is. On the G80 M3 and G82/G83 M4 it delivers unmistakable motorsport presence, and because yellow and white are road-legal in the UK, your main beam stays white and fully compliant.

Fits BMW G80 M3, G82/G83 M4 & G22/G23/G26 4 Series

Designed for the G80 M3, G82 M4 Coupe and G83 M4 Convertible, plus the G22, G23, and G26 4 Series, from 2021 onwards. Suitable for cars with LED or Laserlight headlights, in both Pre-LCI and LCI (2025 facelift) forms. As these use different modules, send us your registration and we will confirm the exact fit before you book.

Frequently Asked Questions

Does the G80 M3 use the same DRL as the M4?
Yes. The G80 M3, G82/G83 M4, and G22/G23/G26 4 Series share the same DRL module, so this upgrade covers the whole family. We confirm the exact Pre-LCI or LCI fit from your registration.

Are yellow DRLs legal in the UK?
Yes. Yellow and white are road-legal because the main beam stays white. Other colours (red, blue, RGB) are intended for show or off-road use only.

Is it plug and play?
Yes. It replaces your existing DRL board using the original connectors, with no coding required.

Will it affect my warranty or MOT?
No. It is fitted without permanent modification and is fully reversible. Road-legal yellow or white DRLs will not fail an MOT.
