Anyways, I use a Nite Ize nite dawg collar, their spot lit "tag light" (as I call them), and a Mendota visi-vest.
For myself, I have my dad's old reflective vest from the AF, as well as a Nite Ize light up belt and hat light (I forget what those two are specifically called- the hat light you just clip to the brim). Can you tell that I like the Nite Ize products, lol?
