Nope. 55 watts is 55 watts no matter if they are halogen or HID. The amperage draw is what you need to look at. Look that info up.
HIDs can pull a max of around 9.2 amps but run about 3.2 amps. So I dont think you would have a problem with the stock wiring. You will have to upgrade the fuse tho.
Yeah I planned on uprgrading the fuse, and it's not stock wiring, its the wiring harness that came with my 55W lights
