Blind Spot Detection System for Audi A4 S4 RS4 B8 8K Avant Dual MmWave Radar Warning Mounted on Rear Bumper
Upgrade your Audi A4 S4 RS4 B8 8K Avant with a precise Blind Spot Detection System with Radar Warning, designed to enhance safety during lane changes and merges. This smart system uses two mmwave radars (two 24G/72G Hz) mounted on the rear bumper to continuously monitor the blind zones and alert you before risk arises. When a moving object enters the set warning area, you’ll receive timely signals through LED indicators, audible prompts, and coordinated signals from the adjacent turn indicator—helping you decide when it’s safe to change lanes.
Built for Audi A4/S4/RS4 B8 8K Avant models from 2008 to 2016, the system offers flexible installation options. If you provide us with the original mirrors, our engineers can customize the laser warning light pattern to perfectly match your mirrors (the product price remains the same; you’ll simply cover shipping and any possible customs duties). The solution supports two mainstream display approaches: a lens-display with a prompt light on the lens, or an in-car display shown on the triangular window inside the car. This versatility ensures a cleaner integration that suits your preference and vehicle styling.
Key features include Lane Change Assist (LCA), Blind Spot Monitoring (BSD), Active Overtaking Warning (AOA), B-pillar blind spot alerts, and Reverse Crossing Warning (RCTA). An optional Door Opening Warning (DOW) adds another layer of protection. The system adapts to speeds up to 120 km/h and provides a warning range of 3 to 10 meters behind the side of the vehicle, giving you ample time to react. It starts up automatically with ACC, so you’re always protected without extra steps.

- Universal LED light installation places the LED on the A-pillar; for special installations, LED lights can be mounted in the blind-area rear-view lens.
