I originally bought these for my Honda dual sport and after seeing how great they held up to the beating of constant bouncing around and crashing off-road I purchased another set for my sport bike. They look sleek and are far brighter than any incandescent bulb on a bike. The power draw across all 4 is extremely low even when I use them as running lights and they're on all the time. The only downside I've noticed is they can spin some even with their mounts tightened down properly but that was easily stopped with a small dab of super glue between the rubber mount and the metal mounting point on the bike.
