Yea, I'm running H11's with no problem at all. They are always on at night and have been for the last month or two. I dont know if they have yellow, here is their facebook,

If they dont have the color you want, check out their LED bulbs. They are almost as bright as HIDs and last 10x longer. I was going to get LEDs but they had a sale on HIDs which made getting a whole new set w/ ballasts cheaper. Good luck!
