I would go with a Clam light bar. It comes with hooks to attach to your frame temporarily, or can be permanently mounted. I googled your shack and it looks like your peak frame section might be too far back to mount lights on, and the front one may be better. You don't want the lights shining in your eyes either. I would buy the light bar that matches your pole sizes (Clam makes two different ones) and use the hooks your first time out so you can move it between frame sections and adjust the angle. once you figure out what works for you, permanently mount it.
