hids

right people, I wanna get hids, chavvy I know but no mot over here so doesn't bother me. ive had 35watt and needed a capacitor thingy to trick the can-bus bulb check so I got the famous flickering. ive been looking at 55watt ballasts but ive found some say can-bus for 21 quid a ballast or 12 for non can-bus. I was thinking if its 55watt I should be fine running standard 55watt ballasts? or would I need the can-bus ones?
