you need to see how the new fogs compare to the standard ones. If they dont draw much more then i wouldnt bother with two batteries etc. Remember youre going to have to fabricate it so that they are securely mounted either in the engine bay or boot and then youve got to think about the charging circuit etc. I almost wouldnt bother and just run it all off one decent battery with a decent working alternator.
