The headlights on a right-hand drive (RHD) vehicle cannot be legally adjusted to comply with the requirements for a left-hand drive (LHD) vehicle. The headlights on a RHD vehicle are pointed towards the right side of the road, in order to provide better illumination of the oncoming traffic and pedestrians. When a RHD vehicle is driven in a LHD country, the headlights will point towards the left side of the road, which can cause glare to other drivers and obstruct their view.
In addition, the headlights on a RHD vehicle are not designed to meet the LHD regulations regarding the beam pattern and intensity. The LHD regulations require the headlights to have a specific cutoff pattern, which ensures that they do not glare or obstruct the vision of other drivers. The headlights on a RHD vehicle do not have this cutoff pattern, and as such they can cause glare and obstruct the vision of other drivers.
