Depends on how much your life is worth to you. I have $350 dollars worth of lights on our two bikes each for a total of $700 dollars in lights, but we feel our lives are worth that amount of money.

We have a Bontrager Ion 700 for the front, a DesignShine 500 on the seat post and two Cygolight Hotshots one on each seat stay to form a triangle of light from the rear.



Can you see me now?
