Something like that, or maybe Dinotte's taillight. Buy a headlight you like. In rural situations the headlight is more about seeing than being seen, and that's a personal choice. You probably will want to spend $200 or more on lights for dark rural riding. There's no city out there to provide lighting for you.
Get yourself some of that reflective tape for your bike, bags, and maybe jacket. Don't go nuts, but a few strips will be good.
Don't go completely crazy, you probably don't need to spend $1k. You may want that money if you decide you need a car for some of the nasty days.
