Full beam bulbs as main headlight

This may be a stupid question, But the previous owner of my 200 has changed the sidelights to these white/blue bulbs. Now the main headlights are the standard boring bulbs, but the full beams bulbs are white aswell.. I was about to buy some white bulbs for the main beams when I thought, can i just swap the full beam bulbs with the headlight bulbs? Or will this be hard to do? and the full beams aren't xenon bulbs whereas the headlights are??
 
what type headlight you got as the 200 never had the option of xenon, and your slightly confusing? you got normal headlights or projectors? (look like a glass ball)
 
Why not just buy some white headlight bulbs so that all the bulbs are then white?

Full beam bulbs will still be the correct bulb then rather than dipped beam bulbs (if you swapped them)
