Officially known as Adaptive Forward Lighting (AFL) and to be launched in Signum and Vectra models in April, the system combines bi-xenon lamps that turn for intersections and tight corners. Amendments to ECE regulations to allow for the introduction of AFL technology – developed jointly by GM and Hella – should get the go-ahead next month.
On corners, the swivelling headlights shine at an angle of up to plus or minus 15 degrees, depending on the steering angle and vehicle sped. Bends are better illuminated by up to 90 per cent.
Additional wide angle lighting provides extra illumination at junctions and narrow bends – nearly 90 degrees to the direction of travel over a distance of about 100ft from the car. This turning light is designed to function only at speeds of up to 30mph so it does not activate in situations like lane changes on the motorway.
Vauxhall says replacement units will be made available to the aftermarket as soon as possible.
