BMW 3 Series G20 G21 G28 LCI Adaptive LED Yellow DRL Board Set 63115A57073 63115A57074

BMW 3 Series G20 G21 G28 LCI Adaptive LED Yellow DRL + Indicator Board Set – 63115A57073 / 63115A57074

Upgrade the factory daytime running light appearance of your BMW 3 Series G20, G21 or market-specific G28 LCI with this complete set of yellow LED DRL + indicator replacement boards.

Designed for compatible BMW LCI Adaptive LED / high-specification headlights using the combined daytime running light and turn-signal modules associated with BMW references 63115A57073 and 63115A57074, these boards replace the original internal LED light-source boards while retaining the original BMW headlight and module housings.

The original BMW modules perform a combined DRL and indicator / turn-signal function. These upgraded boards provide the distinctive yellow DRL light signature while retaining the combined lighting functionality of the original module and headlight assembly.

This yellow DRL appearance is particularly popular for creating the motorsport-inspired lighting style seen on a number of modern BMW performance models.

Vehicle Compatibility

Please note: BMW used several different LED headlight specifications throughout the G20/G21/G28 range. Compatibility should therefore be confirmed using the original module number, connector design and LED board layout rather than the vehicle model or registration year alone.

DRL + Indicator Function

BMW references 63115A57073 and 63115A57074 are used for LED modules that provide the combined turn signal / indicator and daytime running light functions within compatible Adaptive LED headlights.

These replacement LED boards form the internal light-source section of those modules. They are therefore more accurately described as DRL + indicator LED boards rather than DRL-only boards.

The boards are designed to work with the vehicle's existing BMW module housings and headlight assemblies. They are not separate external indicators and are not complete headlight control modules.

Adaptive LED vs Standard LED Headlights

This yellow LED board set is designed around the BMW 63115A57073 / 63115A57074 combined DRL + indicator modules used with compatible Adaptive LED / high-specification G20, G21 and G28 LCI headlights.

Standard / Non-Adaptive LED headlights use a different module and board design associated with references 63115A4F771 / 63115A4F772. Those boards are physically different and should not be confused with this Adaptive LED / High Specification set.

Yellow DRL Upgrade

The factory BMW LED boards normally produce the original white daytime running light appearance. These upgraded LED boards are designed to create a distinctive yellow daytime running light signature while being used within the original combined DRL + indicator module system.

The indicator / turn-signal function remains part of the original combined module design. The styling modification provided by these boards is the distinctive yellow DRL appearance.

This provides an OEM-style internal installation within the existing headlight rather than adding external LED strips or separate lighting units.

Board Dimensions

What's Included?

1 × complete yellow DRL + indicator LED board upgrade set containing 2 LED boards – one board for the left headlight and one board for the right headlight.

This listing is for the replacement LED circuit boards only. Complete headlights, aluminium module housings / heatsinks, headlight control modules and any other components shown for identification or demonstration purposes are not included.

Installation

These are internal headlight lighting components and installation requires access to the existing LED light-source boards within the original DRL + indicator modules.

Before installation, compare the replacement boards, connector contacts and mounting points with the original components. Appropriate thermal interface material should be renewed where required by the original module construction.

We recommend installation by a competent automotive lighting technician or suitably experienced person.

Important Road-Use Information

This product changes the original colour and specification of the vehicle's daytime running light output. Yellow DRLs may not comply with road-lighting or vehicle type-approval requirements in all countries. Buyers should check the regulations applicable to their vehicle and location before using modified lighting on public roads.

For UK/ECE-type-approved applications, daytime running lamps are normally required to emit white light. The yellow DRL conversion should therefore be regarded as a styling / show modification unless its use is permitted under the applicable local regulations.

The vehicle's indicator / turn-signal function should continue to operate correctly following installation and must comply with the applicable road-lighting regulations.
