The SeeEm LED lights are more discreet than other visibility enhancing lights made by nit ize but are a nice accent to increase visibility and "motion" while night riding. My bike looks more like a mobile christmas tree with all the red and green lights rolling around, but it's worth it when cars swerve to clear my space on the road. If you are on a budget, don't bother, just get Flashflight SpokeLit Disc-O they throw more light than the smaller SeeEm's offer. On the other hand if you want to accent already well lit wheels, go for the SeeEm LED's.
