Makes seeing stop lights easier in low cars. For some reason they don't seem to have any of the only product they sell at www.lightinsight.com, but I was able to find one at Detroit Tuned (though more expensive...): https://www.detroittuned.com/light-in-sight/

When looking straight ahead, you can see objects almost straight above you (with enough detail to make out a signal light color):



Hope that helps someone. I have used them over 20 years in my sports cars.

Nothing negative. I've used these for years in other cars.
