Got you covered dude.... I did the same to my MS6 and I got the PIAA Ion Crystal yellow bulbs, cost me around $60 the pair, got the at a place called TAV Racing in Miami (305) 591-8544 they can probably ship them to you.
Hope this can help.
I bought Nokya Hyper Yellow H1 bulbs looks amazing...
j/ remember to buy "55W", on the display box,
it will say 80W, that is j/ the output,
authentic Nokya bulb should have the Watts engraved to
their metail piece of the bulb.....and the one
i purchased and advice u to purchase is 55W engraved
