It's pretty easy, you need a "taillight integrator" which can be bought from many motorcycle stores.
Your local automotive store will probobly also have the same thing, but for cars towing trailers. (look around the trailer/towing section, Uhaul has them as well)
Its a little box that has input wires for your blinkers and brakes, and then output wires that goto the tailights.
I used to have one on my bike, but it was hard to see the blinkers in daylight, and I did not feel safe like that, so I took mine out.
