..FYI, there are some nice LED light sticks on Ebay for use as a high mounted brake light. With the addition of a spacer this could go under a louver and clear the rib. It's lightweight, adheasive mountable and adjustable for directing the brightest light to the rear. This adjsutability means it could also be mounted many other places like on the grill behind the louver or even inside the rear window. I just put one on mine at it looks great. Cheaper than the corvette or SUV GM ones also. Search on "36 LED Light Stick" to find it.
