I also ordered a set of lenses and had trouble with the buttons binding on both of our empegs, I used a dremel to elongate the screw holes on the knob side (the screw holes were too close together left to right). The stock lens works fine in my CRX, but in my wife's Element, the empeg is up near the top of the dash and is very exposed. Any bright day totally washes out the stock lens. She now has the bronze lens and that works great! I wanted to use the red lens in my CRX, but the red one is just too dim (I could only see it well in my garage or at night), I am suprised anyone is able to use it in a car environment. I now use the smoke one. It is very bright and I can use it in my wife's car (when I can get it away from her). Thanks again for a great job!
