Would you not get a better or similar front effect of having a light on your bars then attaching 4 led lights in a line on your fork. One at top of fork, one at bottom and then two somewhere in middle.
You then have a line of 5 LEDs. The same effect from the front of these revolights.
You can also move the lights onto your other bikes. As a lot of cyclists like me have more than one bike.
Too be honest I don't mind spending the money on good lights, I have a exposure Diablo and joystick on he front and two exposure flares on the rear. At least these are waterproof not water resistant.
And the 5 led system of mine would be a fraction of the cost too.
