If you have the path lights with the spike, extend them with pipes the spikes will fit inside.
Or, use string lights run between posts or pipes. We used the ball lights between 2x2s hammered into the ground in two runs about 10” apart to outline a path to our burn-pit area during a party a couple years ago. We hooked them on with the little Christmas light clips. We used the ones where you can plug several runs end to end so it was easy-peasy. I don’t have a picture, but it looked similar to the theater rope pathways with two rows of rope, one at knee height-ish and one at waist height-ish.
I think that it might look cool to incorporate both, even.
Hope you’ll post pictures of whatever you come up with.
