So you're good the LED's for the interior (good call Rooz, that's pretty flippin sweet)...
... for the corners, I agree, go clear or smoked. And for your bulbs, I HIGHLY recommend the APC silver bulbs. You can get all six (front, side and rear directionals) pretty cheap ( I got my set of six for under $50.00 shipped) and you wont get that nasty orange "egg yolk" look. Here's a link to a set from eBay...
