They are having a 40% off sale today with code PRIMEDAY17. They seem to have a similar sale once a year or so. I have no affiliation with this company or any of their employees. I've been using the product for the past three years or so and have been pretty happy with it.

I'm also intrigued by Tern's Vizy Light, a rear light that throws a halo of red light onto the ground. I haven't ordered one yet, but it does look very interesting. No affiliation with Tern, either.
