the other location for a 3rd brake light would depend on how the rear anchor points for the top are attached. I was thinking pull the anchors, create the third light to fit between and under them and taper the ends out part the anchors. This way it's nearly invisible while not lit up and all but the lense of the light is covered by the top, tonneau, or boot cover. However, this idea would only work if the anchors are held in place with screws... I haven't looked too far into doing it just yet, because I've had other things occupying my time.
