Why Adaptive and Matrix Lights Complicate Auxiliary Light Installation
Modern vehicles often come equipped with adaptive or matrix headlights, which adjust beam patterns based on driving conditions. While this improves visibility and safety, it also introduces complexity when adding aftermarket auxiliary lights.
Traditional auxiliary light installs relied on tapping into a 12V high beam signal. With adaptive systems, there’s no longer a physical signal to detect. Instead, activation is managed digitally via CAN-bus communication between the car’s ECUs.
This creates a challenge for workshops and installers. Without a proper CAN-bus reader, there's no reliable way to detect when the high beams are truly active — and triggering auxiliary lights incorrectly can result in malfunctions, dashboard errors, or even legal compliance issues.
Styrestrøm modules solve this by decoding high beam activation directly from the vehicle’s CAN-bus, even when matrix and adaptive systems are in use. Our modules ensure correct triggering and legal operation, with no need to cut wires or compromise the car’s electronics.
