LED Headlight Diode Control Module With DRL And Turn Signal For Audi A3 S3 RS3 8V0998473 8V0998474
Upgrade your vehicle’s lighting architecture with this LED Headlight Diode Control Module, engineered as a direct replacement for OEM part numbers 8V0998473 and 8V0998474. Designed specifically for Audi platforms with integrated daytime running lights and turn signal sequencing, this electronic ballast unit manages current flow to prevent error messages and restore full headlamp functionality. When the original control circuit degrades from moisture exposure, voltage spikes, or internal semiconductor failure, this aftermarket module reestablishes precise DRL brightness and dynamic signaling without requiring wiring modifications. Rigorously validated against factory pinouts and thermally rated for harsh engine bay conditions, it delivers reliable daytime visibility and compliant road positioning.
Benefits & Usage Tips
- Direct bolt-in replacement preserves factory adaptive lighting routines while eliminating ghost chimes or headlight fault indicators on the instrument cluster.
- Rated for continuous operation between –40°C and 125°C, ensuring consistent diode modulation even during prolonged highway cruising or winter cold starts.
- Match both left and right units when servicing dual-side damage; confirm the D1S socket orientation before securing the bracket to avoid reverse-polarity connector strain.
