I got a cheapo hiker's headlamp from Job lot and zip tied it to my helmet for winter - what's nice is when my head moves, the light moves. I also have a headlight on the bike, and a red taillight, and reflective tape all over the place. If I'm going on the long commute, I'll wear a mini mag flashlight on a necklace over my back - it illuminates my high-vis jacket (which has reflective piping) and my bag, which also has reflectors. I also wear reflective ankle straps.

It's still not enough.

But I'll tell you, we drove on Halloween out to Western CT on route 44 - a "country drive" on our way to a b&b weekend. A few country towns were having Halloween events for kids and there were trick-or-treaters all over the place. You just can't see people. They just blended right in with the trees, parked cars, whatever. Put refective tape on your kids' Halloween costumes, PLEASE!
