To avoid any confusion - FMVSS108 (the US federal standard) does not require self levelling headlamps or headlight washers, that is an EU (European Union) requirement, which the UK (United Kingdom) as a member of EU must adhere to, in the same manner as the US states are required to adhere to federal standards.
EU have their own lighting standards which are equivalent to the US DOT requirements, and HID conversions and retrofits are also not permitted there - adding auto levelers & headlight washers would not be sufficient to make the vehicle road legal - not in the US and not in the UK or Europe.
Most countries in the developed world have similar regulations forbidding the use of HID conversions & retrofits.
