Just in case anyone is curious, I got the flat mount less that VDC suggested and they look pretty good. They just came in yesterday so obviously I haven't installed them yet, but I hooked them up to a 9v battery just to see how they looked, and they were plenty bright.
I'm going to use these white ones for interior footwell lighting to be hooked up with the map lights so that when they come on automatically (unlock the car, open the door) the footwells will light up as well.
This is one red led, I'll have two red and two blue leds in each projector (going with the dual projector look)
And finally I hooked up the halos to a 9v as well just for fun, they're super bright.
You like how my leg is all weird shaped? Yeah, motorcycle accident. Blah.
