Query: A "To Be Seen" light, not so much a "To See" light

Bike lights generally fall in to two categories: "to see" or "to be seen". This light does illuminate a bit in front of you but not enough to go fast in the dark without worrying about hitting something. The light is surprisingly small (about the size of two fingers).The switch is very well designed in that you hit it once and the light turns on solid, hit it again and the light blinks, hit it a third time and the light goes back to solid. This is nice if your ride takes you alternately through well lit high-traffic areas (blinking mode) and dark low-traffic areas. To turn the light off you hold the switch down for a couple of seconds. This way you never accidentally turn the light off when changing modes.Light is not very water-proof. I left the light on when I washed my bike and the insides were soaked. Worked just fine after it dried.Mount could be studier...but it is OK.
