High mounted stop lamp
I have noticed that when the 7 pin umbilical cable is connected from the tow vehicle to the Que, the high mounted stop lamp blinks about every 5-10 seconds. I have determined (I think) that the lamp blinks because the Prodigy brake controller I use is constantly testing the electric brakes to be sure they are still connected. This has been the same with two different trucks, one Ford and one Toyota. I also know that when we drive down the road the high mounted light is blinking at the same rate, night or day. A friend happened to follow us down the road the other day and noticed the blinking light, but also noted that he never saw the high mounted light come on steady when I braked the trailer.
I did an experiment with the brakes, and found that manually applying the trailer brakes with the controller lever did actuate the high mounted stop light. However, just pressing the brake pedal DID NOT actuate the high mounted light unless I used the "boost" function of the prodigy controller. I believe that when actually stopping, the light probably does come on if there is enough braking voltage applied to the trailer brakes, although I still have to experiment with this.
Has anyone noticed or experimented with this issue? I kind of like the blinking stop light at night, since it is easy to find the Que in the dark amongst all of the RV's in a park!
