These are great! I have trouble driving at night. The oncoming headlights all but blind me! The new and popular halogen headlights and large truck headlights are a danger to me when driving. The amber clip ons change all of that! By altering the wavelength of light that hits my eye, I am able to drive safely at night. I tried the visor version of this but there was too much reflection. I give these two thumbs up!
