8S4 is added to all US cars equipped with Adaptive Front Lighting to disable (decode) the ROW Low Beam Light Distribution patterns. This is due to regulations restricting their use so US Bi-Xenon Projectors do not contain a multi-position roller assembly. Partial functionality of VLD can be coded in by removing 8S4, however the beam shaping is not possible. Only the swiveling and beam throw are possible. Glare-Free/No-Dazzle High Beams are completely different and proper functionality is not possible with US Bi-Xenon headlamps even with enabling codes applied.
