I know quite a few of the owners have installed a 30 LED, 16" long by 1" high 3rd brake light from GM SUV's. I installed mine on the rear top of the second louver from the top where it does not obscure vision from inside. I did a No No and drilled two holes in the louver using the two bolts to fasten mine. That way they are flush and good and solid....I painted the nuts and bolts flat black first and you just cannot see them from the rear without really looking for them. The wires are easily concealed completely and run back within the right side Stainless Steel panel and on into the right rear tail light assembly. Be careful of the polarity...at first mine was dead until the light dawned that these were not your ordinary 12 volt filament type bulbs! They look like factory and are really bright. Only drawback is that the cost was about $80. Murray Vin: 05962 Lic: DMC-XII
