What's the difference between "look out" and "watch out"?

At times you could use either to mean the same thing. Like here, you could use either. But perhaps more specifically, "look out" means to be aware of something specific, "watch out" is more general. Ex: Leonard, watch out! = Leonard, look out! Ex: You should look out for the taco cart when you go to the fair. Ex: Watch out! You don't want a bike to crash into you.
