You'll want the smaller, flatter type. Not sure what else to call them?!? Definitely not the old type where they are covered with a dome like plastic cap.
Try and find out what angle/degree light is visible from them in their spec sheet. The wider the better. I'd say that you want to try and use as many as you can neatly. Those small replacement led globes look terrible and give bad visibility.
I'm sticking with normal globes on this build- No ADR's on homemade lights i wouldn't think..
