question about l.e.d lights & requirements

[mxdad316]

I have a 2001 300xc, with 2k-2 stator. I want more light, no intrest in dual sporting just off road. I have seen a lot of l.e.d. lights on e-bay I thought about trying. One kit was shaped like the headlight lense itself with 5 or 6 led's in it, & I kinda liked it. What would be involved in installing this in place of the stock headlight? I read a lot of posts about the floating ground mod, & I'm not sure if I would have to do that for what I want. I remember reading someone (GMP maybe?) wanted to put a couple of led spots on with a capacitor & no battery but I never heard if it was done successfully. Any info is appreciated!
