inpro hid's???

[capri 0]

hi, ive just bought a set of second hand inpro projectors off ebay and ive run into a slight problem. my existing h4 hid's that i was running on the standard lamps dont fit in the projectors as theyre too big. theres no markings to say what bulb i should be using so i was wondering if any of u guys know what bulb to use and if i can simply change the bulb on my ballast or do i have to but a whole new set of hid's???

thanks in advance
