BMW G20 & G21 3 Series CSL Yellow DRL Module

Transform your BMW G20 or G21 3 Series with the iconic CSL yellow daytime running light signature, inspired by the legendary G82 M4 CSL. This DRL module replaces your factory white DRLs with a bold, motorsport-inspired yellow that instantly sharpens the front of the car. Plug and play, professionally fitted at our East London workshop.

The CSL Yellow Look for Your G20

The G82 M4 CSL made the yellow DRL an icon, and now you can have that same aggressive signature on your 3 Series. It is one of the most striking and cost-effective ways to set your G20 apart, and because yellow and white are road-legal in the UK, your main beam stays white and compliant.

Fits BMW G20 & G21 (Pre-LCI and LCI)

Designed for the G20 Saloon and G21 Touring 3 Series, in both Pre-LCI (2019 to 2022) and LCI (2023 onwards) forms. Suitable for cars with LED or Laserlight headlights. Pre-LCI and LCI use different modules, so send us your registration and we will confirm the exact fit before you book.

Frequently Asked Questions

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

Will it fit my G20 3 Series?
It fits the G20 and G21 with LED or Laserlight headlights, in both Pre-LCI and LCI forms. As these use different modules, send us your registration for a fitment check before booking.

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

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.
