You can also get a reflector mount that fits your seat says and integrate that with the K-edge top cap mount without too much trouble.

If you don't care about the light, the radar works fine in a jersey pocket.

I've had all the versions of the varia radars. As long as you understand that it shows differences in speed and you always look before you cross the lane, it's a great tool. It's most useful in open country or rural riding. In the city or urban/high traffic areas it's not too useful - just too much information. Overall, we really like ours so that I got one for my wife for Christmas.
