When should someone have lights? I don't ride at night, strictly a recreational rider who unless something drastic happens won't be out after dark but often the daylight is starting to dim and some places heavily wooded area it's pretty dim sooner. I haven't needed lights to guide my way home, I can see fine but I worry less about me hitting what I can't see and more about being hit because I was seen.

I have a small cheap set I picked up a K-Mart on close out for (I think) $4.00 2 LED Flash Light Reflector Cycling Bicycle Head Front Rear Wheel Silicone ME307 | eBay . I keep them in my under-the-seat bag in case I need them. My question is, when should I get them out and have them on?
