Lighting HELP!!

[momciltahoe]

Hi guys I am ordering fog lights for my recently purchased 2007 tahoe wondering if anyone knows of what kind and where to order some Halo fog lights with an HID kit to match my halo headlights. Also what HID to go with for both I travel down dark country roads and need something to lights it up I was debating between 6K or 8K no sure which to go with I see on alot of post people have been going with the 6K was wondering why over the 8K?? Hoping to get alot down to the truck starting with the lights outside then switching out to LED's throughout the interior once I figure out which of those bulbs I need to get and from where that are decently priced and will last.. Any help is greatly appreciated!! Need to make profiel and will poist pics as changes start happening..

Thanks Guys
