CHMSL on a Trailer?

It has long been a requirement that vehicles have what the NHTSA calls a Center High-Mounted Stop Light (CHMSL) to improve visibility in traffic. I'm considering adding one to the back of our TT and starting to noodle about how I might wire it up so it doesn't blink with the turn signals.

I've noticed over the years how effective these lights are in traffic...especially when you are following an SUV, van or other tall vehicle that blocks your view of the tail lights on the vehicle ahead of him. It really helps you watch who's doing what in heavy traffic, and I've noticed that some heavy dump trucks and other commercial vehicles are adding stop lights higher up on the truck body.
