Note that in the homebrew world, lagers are one of the most difficult styles to produce and clone, requiring pretty precise temperature control during fermentation. If you don't have the means to control the temp at about 56 for a few weeks then 34-36 for 4-6 weeks after that, you are not going to be able to produce a good bud light clone.
In lagers, fermentation temp is everything!
Also, unless you are buying in bulk grains, harvesting yeast, etc., it is typically cheaper to buy it at the store than it is to homebrew it. That's why most of the peeps are giving you crap...what's the point in trying to clone Bud Light Premium or any other cheap, mass produced swill, when you can buy it up the street. Most homebrewers would rather make an original recipe craft lager and leave the yellow stuff to the multi-national corporations.
I don't know if you are an experienced brewer, but I can tell you that if you are not, then it is going to be very very difficult for you to clone something like a Bud Light Premium. You'll make beer, but it is just difficult to do all of the things they do without their facilities, especially their mass filtering machines.
