More about lights- you need to have lights on yourself and your bike, enough on all sides so you are clearly visible from every angle (a headlamp does no good if someone is coming up on you from behind). The good news is that the price of led strands is low enough that you can easily buy a bunch on Amazon for fairly cheap. Here is a link to strands I've used in the past:

These are lightweight, can easily be applied to any outfit with safety pins, and can be attached to a bike frame and wheels using electrical tape. (No need to remove them when you're away from your bike, I've never heard of anyone taking the time to peel off electrical tape to steal these lights). They run on standard watch batteries, so bring some spares and you should be good to go.
