superbrightleds.com is where I was going to get all the components, very good company, I used them making a set of led taillights for a friends 89 supra. I also had a great experience with them.
LEDs are brighter but with the back up lights, standard bulbs give more distance I think. I am using 3000s in the brake and signal lights with them dimmed for the running lights, also considering going ahead a making the front turn signals LED while I'm doing the work.
