HELP needed: 94 S500 to convert to Xenon

[S-classmate]

Hi everybody,

Please help! I am new to this forum. I have a 1994 S500. I really want to update my halogen headlights to Xenon. It all started when I found my headlight lens has a big stone/rock chip, from which leads to the thought of replacing the headlamps to ones with projectors buying online:

However the euro style headlamps seem to have Hi/Lo beams separated with the high beam at where the fog lights used to be and fog light has it own compartment tuck right under the Lo-beam...and looks like there is another light(unknown purpose) just under the new position of the Hi-beam as well. Currently the headlight is H4 halogen with both Hi/Lo in one bulb. Can the Hi/Lo be split after I convert to Xenon?(with Hi-beam split out as a halogen bulb (but what type?) and still be able to operated from inside the car as before?? Or, the only way is to go with those Bi-Xenon HID with Hi/Lo both in one bulb:

but any disadvantage with Bi-Xenon bulbs? Sounds too good to be true. But with Bi-Xenon, there will be 2 unused lights in each side. Is it normal? Please help.

ps. Do I have to disconnect and lose some self-leveling feature with these aftermarket headlights??
