Audi A3 S3 RS3 8V LED DRL & Indicator Board Set 8V0998473A 8V0998474A

Audi A3 S3 RS3 8V LED DRL & Indicator Board Set 8V0998473A 8V0998474A

Complete 4-piece LED DRL and indicator light-source board repair set for selected Audi A3, S3 and RS3 8V facelift LED headlights. The set covers both left and right headlamps and is designed for applications using the associated 8V0 998 473A (left) and 8V0 998 474A (right) LED-unit references.

Each compatible headlamp uses two internal LED light-source boards: one board for the daytime running light (DRL) and one board for the indicator / turn-signal function. This complete kit therefore contains all four boards required to service both headlamps.

Ideal for repairing compatible Audi LED headlights where the original internal DRL or indicator light source has failed, allowing the original headlamp assembly to be retained rather than replacing the complete lamp.

Complete 4-Piece Left & Right Set

The package contains four LED circuit boards, covering both the left and right headlights:

• 1 x Left DRL LED board – black 8-pin connector
• 1 x Left indicator / turn-signal LED board – cream 8-pin connector
• 1 x Right DRL LED board – black 8-pin connector
• 1 x Right indicator / turn-signal LED board – cream 8-pin connector

The smaller boards are clearly marked LEFT DRL and RIGHT DRL, making it easier to identify the correct installation side.

DRL & Indicator Functions

Each compatible Audi LED headlamp uses two separate LED light sources:

• Daytime Running Light (DRL) – provides the white LED daytime-running-light function.
• Indicator / Turn Signal – provides the amber direction-indicator function.

The complete four-board set therefore services the DRL and indicator functions on both the left and right headlights.

OE Reference Numbers

Please note: 8V0998473A and 8V0998474A are the associated left and right LED-unit references. They do not identify the DRL and indicator boards individually. Each side of this repair kit contains both a DRL board and an indicator board.

This product is supplied as a set of new aftermarket internal LED PCB repair boards. It is not a complete Audi LED module, heat sink or complete headlamp assembly.

Vehicle Compatibility

Designed for selected Audi A3, S3 and RS3 8V facelift models fitted with compatible LED headlights.

*Fitment depends on the exact LED headlamp specification fitted to the vehicle. Please confirm the original OE reference, PCB shape and connector configuration before ordering.

Board Dimensions

Dimensions are approximate and should be used together with the product photographs, PCB layout and connector design when identifying the correct replacement boards.

Left & Right Identification

Installation

These boards are fitted internally within the headlamp assembly. Installation requires access to the rear/internal LED light-source section of the headlamp and replacement of the original PCB.

We recommend installation by an automotive lighting specialist or competent technician familiar with LED headlamp repair and electronic components.

Always disconnect the vehicle battery where appropriate and observe suitable anti-static precautions when handling electronic circuit boards.

Before Ordering

Please compare your original components carefully with the listing photographs before purchasing. In particular, check:

• Associated OE reference 8V0 998 473A / 8V0 998 474A
• Vehicle has the correct LED headlamp specification
• Left and right PCB layout
• Black 8-pin DRL board connector
• Cream 8-pin indicator board connector
• PCB dimensions
• Mounting-hole positions
• LED and component layout

Do not rely on vehicle year alone. Audi fitted different headlamp variants within the A3/S3/RS3 8V range.

If you are unsure about compatibility, please contact HIDS-DIRECT with your vehicle registration or VIN together with clear photographs of the original headlamp and LED boards. We will be happy to assist with identification.
