From what I have read, Variable Light Decoding means a headlamp design that supports not just turning with steering input but beam pattern reshaping with speed. In other words the headlamp supports changing the bulb's position with respect to the focal point and projector lens within the headlamp assembly. This has the effect of altering the beam shape as it illuminates the road ahead. Slower speeds yield a broader, shorter distance pattern and higher speeds yield a narrower, longer distance pattern.
