In my suburban area, I'm fortunate that bike theft doesn't seem to be a problem at all. I've given up locking my bike at work (gated facility with 24/7 security; I just leave it in a parking deck stairwell, tucked under an overhang where it's not in anybody's way), and although I do lock it up if I'm doing errands about town, I feel like I could probably get away with just leaving it in bike racks unlocked (but don't want to find out the hard way I'm wrong!)
Anyways, lights. I have a cheap but very effective
LED flashlight "permanently" mounted onto my handlebars with interlocking hose clamps. Anybody with an adjustable wrench or flathead screwdriver could get it off in a minute, but I doubt anybody around here has even noticed it's there. I feel like the car-centric SoCal culture has bike blindness.
