If you can't be bothered to research the facts yourself .. these may assist..

Head light levelling ..

"Internationalised ECE Regulation 48, in force in most of the world outside North America, currently specifies a limited range within which the vertical aim of the headlamps must be maintained under various vehicle load conditions; if the vehicle isn't equipped with an adaptive suspension sufficient to keep the headlamps aimed correctly regardless of load, a headlamp leveling system is required. The regulation stipulates a more stringent version of this antiglare measure if the vehicle has headlamps with low beam light source(s) that produce more than 2,000 lumens – xenon bulbs and certain high-power halogens, for example. Such vehicles must be equipped with headlamp self-leveling systems that sense the vehicle's degree of squat due to cargo load and road inclination, and automatically adjust the headlamps' vertical aim to keep the beam correctly oriented without any action required by the driver."

Headlamp cleaning

Dirt buildup on headlamp lenses increases glare to other road users, even at levels too low to reduce seeing performance significantly for the driver. Therefore, headlamp lens cleaners are required by ECE Regulation 48 on vehicles equipped with low-beam headlamps using light sources that have a reference luminous flux of 2,000 lumens or more. This includes all HID headlamps and some high-power halogen units. Some cars have lens cleaners fitted even where the regulations do not require them. North America, for example, does not use ECE regulations, and FMVSS 108 does not require lens cleaners on any headlamps, though they are permitted.

As said ideally retrofit using ALL oem kit, ie self levelling suspension/headlights and headlight washers.

Why?

Self levelling suspension is not a requirement for Hid systems.

Agreed .. self levelling HEADLAMPS are however ...  so .. if the suspension can act fast enough to maintain the requirement...

"Such vehicles must be equipped with headlamp self-leveling systems that sense the vehicle's degree of squat due to cargo load and road inclination, and automatically adjust the headlamps' vertical aim to keep the beam correctly oriented without any action required by the driver."

...then I guess they would be acceptable, however I would think that the response time would be too slow... but then I know nothing ......

Yep, thats why I indicated both self levelling kights and suspension.  But as you say you and I know nothing compared to the last word poster

Your right there

No way sl suspension is fast enough, why would gm fit it to hid cars? Because its for the rear ride height. NOTHING at ALL to do with hids.

What are kights? Btw?
