The main reason I went with Hyper-Lites is that just one light on the back of a vehicle does not give following drivers anything to triangulate on to determine distance. About 20% of women and a smaller percentage of men have an eye condition where they can not tell how far away a red light is from them at night. I was married to one of those women. She said that at night, a red light could be 30' or 300' away and it had the same intensity. At the time I was married to her, two riders were killed by women drivers hitting them from the rear, at night, on rural freeways. I immediately installed a Priority Lite device on every bike from then on, but it won't work (without difficulty) on the Cross bike's LED signals. So I went with Hyper-Lites.
So now I have the added safety of those behind me knowing how far I am from them, PLUS very bright flashing whenever I apply my brakes. They flash about 5 times, them go on steady. When I'm stopped at a traffic light, I watch my mirrors for cars and as one approaches, I apply the brakes to initiate the flashing.
As far as the installation goes, its very straight forward. I think you can go into their web site and look at the instructions. I'm 75 and no electrical engineer and I did it. If I recall, there are only 3 connections to the bike: tail light, brake light and ground.
