As well you can look at a lit spreader bar from Drifta in Australia. I have one and it's great. Also solves the awning flapping in the wind and water pooling on the top issues. Huge downside is trying to get it here from Australia is a huge pain.
Another solution is to mount a LED light to the back of the awning or to your truck/rack so that it's below the awning. This would serve the dual purpose of lighting the awning area and work/scene lighting for setting up camp. If you have it on a power distribution hub like an SPod you can dim it as well.
There's also numerous 12v light strip type solutions out there.
