Every colour. One board. Only at NightLine.

The NightLine RGB DRL Boards for the SEAT Leon MK3, MK3.5 and MK4 replace your factory daytime running light boards with a fully controllable RGB unit — switching between red, blue, green, white and every colour in between. Static, dynamic, reactive — you control it via the app.

These are not external LED strips or aftermarket halos. The boards replace your OEM DRL boards directly, giving you a clean, factory-integrated look with none of the messy wiring or external fittings that come with cheaper alternatives.

Important: Professional installation is strongly recommended. If you're unsure whether these are compatible with your specific headlight variant, send us a photo of your headlight unit and we'll confirm fitment before your order is placed.

- Limited Run — 60 Units Only. Once this batch sells out, this product will be removed until a future production run.

Please allow 7–12 days before dispatch. Each set is built to order. Tracking confirmation will be sent once your order ships.

Fits: SEAT Leon MK3 / MK3.5 FR & Cupra (2012–2020) — SEAT Leon MK4 (2020–present)
