2008 MDX Replacement Bulbs for Fog and DRL

Can anyone please help me out here. I want to replace my fog lights with HID's. I am new to this and someone told me don't get HID's unless they are digital? Is it really worth the extra money?....I also want my daytime running lights to be brighter. Is a regular pair of LED bulbs the way to go.

I would appreciate specific reccomendations of name brands and what not. I am down to invest a few bucks for a clean look, i just don't wanna be wasting any money.

Thanks to all that can help.
