BMW CSL Yellow DRL Upgrade UK 2026 — Complete Guide

The CSL-style yellow daytime running lights are one of the most popular BMW modifications in the UK right now. Originally seen on the limited-edition M4 CSL, the yellow DRL signature is now available as an aftermarket upgrade for a wide range of BMW models. Here's everything you need to know.

What Are CSL Yellow DRLs?

CSL yellow DRLs replace the standard white daytime running light colour with the distinctive yellow/amber signature made famous by the BMW M4 CSL. The upgrade uses a plug-and-play module that changes the light colour without replacing the entire headlight unit.

Are Yellow DRLs Legal in the UK?

DRL regulations in the UK require daytime running lights to emit white or yellow light. Yellow/amber DRLs are generally considered compliant for daytime use. However, regulations can vary by specific application and usage. We recommend customers confirm road-use compliance for their specific vehicle and use case.

Yellow DRL vs RGB DRL — Which Should I Choose?

Yellow DRL: A single colour change to the iconic CSL amber. Clean, consistent, motorsport-inspired. The most popular choice.

RGB DRL: App-controlled multi-colour DRLs. Change between colours whenever you want. More customisable but check road-use regulations for non-white/amber colours.
