I worked several year where it was dark when I went to work and dark when I left. Lighting up the bike helps.
I had wheel decals and leds and some reflecting decals around the bike. The leds really light up the reflective decals. Had lots of comments on it.
Be vigilent but don't be scared. Sometimes driving down a quite backroad at 4am is peaceful, as for animals, pay attention and hope they have no interest in taking you out as you ride by.
Don't sweat the petty things; Pet the sweaty things !!!
