I bought these in black and I'm pretty pleased. Attaches with a screw-cog like a lot of lights. Haven't used the front one yet, but on an 8 mile spring commute the rear kept all but one splatter off my back. And I think that's only because it swings a bit, so I'm just gonna stick a rubber strip in there (don't know why it didn't come with one) and it'll stay put better. They're really easy to transfer bikes. Also, they're better looking than most of the plastic space-agy ones.
