Correct. They are going to be fine IF you have headlight washers and a self levelling mechanism installed. Which can either be on the light units or on the suspension.
Otherwise they are illegal. Halogen projectors are not good enough as they have different openings and cut off points. So you will need genuine Xenon units. Normal headlights are not good enough due to beam scatter when installed and glare to other road users.
Basically, if you are going to do it, then do it properly with everything included or don't bother at all.
