On my bike I have two 3-LED CatEye taillights mounted on the belt clips to the pannier bags, I have a third 5-LED CatEye taillight mounted just under my pannier rack. All three are easily visible to anyone who is behind me. I also have a PB Superflash mounted to the back of my helmet, and a CatEye Rapid 3 mounted to the left side of my bike as a running light. I need to pick up a second Rapid 3 to mount on the right side of my bike.

I also have 4 CatEye Uno headlights mounted to the front of my bike. Two on the handlebars and two on the fork, and a Light and Motion Stella 150L mounted to my helmet.
