I have a Light and Motion solo mv. I would not recommend it. Here's why:

The handle bar holder does not lock in the light at whatever angle you need (down, straight ahead, etc..). It is continually shifting from where I want it due to road vibrations.
The light bulbs are impossible to get except through L&M's website at a premium cost for the light bulb and shipping.
Poor life span of the light bulb. The light bulb did not last a season, running at the spec'd 13Watts for less than 50 hours of use.

I would definitely look elsewhere than L&M. It does not matter how nice and bright a light is, if you can't get replacement bulbs easily, if they don't last, and if the holder keeps going out of adjustment.
