HID Low and High Beam Question

[SpoolinGLH]

I am thinking about converting over to HID but just have a few questions before I do.

If I want Low and High Beams do I just get 2 sets (4 ballasts) of HID kits and maybe do 35 watt for the low beam and 55 watt for the high?


If I just do the HID for my low beams will my Stock halogen High beams still work?


Thanks Guys BTW its an 01 Alero if that makes any difference...
