We like to string up christmas rope lights on the ground around the td. It gives enough light so you won't stumble and fall trying to find the potty. FYI...I use a bumper dumper that fits in the receiver hitch of my Jeep Wrangler. I am a big ole Texan and the luggable loo or a port a potty is just too small for me.
The bumper dumper embarrasses my family but I always put it up in the daytime. When you gotta go...you gotta go.
