h1/h1 headlights

i reacently bought a set of new glass headlights for my 96 passat and the said that they use h1 bulbs for both high and low beams how can i convert this to work on my car? i already bought new blue bulbs for it that are h1 and h7? can i just use them or do i have to use both h1's in both beams?
thanx
