3rd Brake Light
Has anyone installed a 3rd brake light to the back of their rv? If so which one and where did you put it?

Since I have never understood the need for one on any other vehicle, no, I have not installed one on my coach, and have no plans to do so.
I haven't even hooked up the one on my pickup topper.
I had to remove the one on the Jeep I had, to clear the oversize spare tire. I never re-installed it. The Jeep is gone, but the light is still laying either in my shop or my son's shop.
Research done by the Highway Traffic Safety Institute in Ann Arbor back in the last 70's showed adding a third brake light at eye level reduced rear end collisions. The also studied the effects of lowering the speed limit to 55 and it showed reduced accidents. However, as they continued to collect data after these two things went into effect they noticed that the rear end collisions and accidents causes by speed were going back up. Their conclusion at the time was that people became accustomed to the 3rd brake light and no longer being unique, the effectiveness wore off. As for speed, they concluded that drivers tend to settle in to a mental state that is about 10 to 15 mph below the posted speed. So lowering the speed limit had a temporary effect until drivers readjusted the mental awareness to the lower limits.
