Re the 3rd brake light.....I know that no one would be as dumb as me in hooking it up, and I have been working with car wiring and electronics in general most of my 81 years. I plumb forgot that LED's are polarized.....thought I was working with regular 12 volt light bulbs I guess....Took me a while to figure why, after I got all the wiring beautifully concealed, that the reason it would not work was that I had the polarity backwards!! Mine is one several have recommended and looks fine. It has 30 LEDs and is from a GM type Suburban. However that one the guys talk about with LED's that light up the car behind you sounds even better!! Murray Fisher Vin: 05962 Lic: DMC-XII
