What's the best simple lighting gear for a single person doing run n' gun filming?

I'm starting a project next year where I'll often be by myself, doing sound and image. I want a few simple lights to carry around. Given space concerns, I'd want them to be versatile and smallish.

I have no idea where to start about a basic traveling kit. I realize this is somewhat vague but I'm just trying to get some ideas at this point. So, any thoughts here are appreciated.
