One advantage of having reflectors/reflective tape on stakes is that visiting drivers should notice the sound of driving through them even if they have their lights off.
How about solar powered garden lights? Might not be an affordable idea if you want lots of them, and you'd have to modify some LEDs to red.
We have the solar garden lights at the head of our driveway, two on each side, about ten feet off the road. They work great, I put them out there 4-5 years ago, and they were only $15-20 for all four. Only one is working reliably anymore, two are just about gone, and the fourth one was smashed to bits by a good-samaritan neighbor who plowed our driveway with a tractor and blade one winter and ran over it.
I'll probably replace them this summer, LED, solar panel, and battery technology might have progressed enough in the last five years that I might get a little more light and a little more runtime out of a new set, I hope so at least. The ones I have now will often go dark by 3-4am during the winter because of the many overcast days and the shorter daylight hours.
The biggest pain with reflectors on stakes and the solar powered lights is mowing and trimming around them every week during the warmer months. Worth the bother in my case though.
