Don't buy a kit. Kits are for suckers and they almost always look like clown puke garbage.

Go to comet, buy a bunch of 2smd sunlight LED's for the GI. Buy 1 SMD or Retro bulbs in sunlight for the backbox (or you can use the 2 SMD I just like dimmer bulbs in the backbox so I get less glare). Then you can either color match the inserts (use pink or warm white under orange and yellow, do not use orange or yellow LED's, they are DIM) with 2 SMD bulbs, or take the easy way out and buy all warm white 2 smd bulbs for under the inserts. Both will look great! Pretty much only use frosted bulbs for everything.
