We read this article that explains night time visibility using window films.
Our FormulaOne Pinnacle and Stratos (Nano- ceramic) films are the least reflective window films available in the marketplace (that can never turn purple!)
There are low reflective dyed films that appear beautiful when they are installed but quickly degrade to purple as their dyes migrate.
Stratos Films reject a greater percentage of the invisible heat (infrared!) so a lighter 35% transmission film will reject more total solar energy than darker reflective metal films of similar light transmissions.
Proprietary non-metallized, nonconductive nano-ceramic technology maximizes heat and ultraviolet rejection, keeping you and your vehicle cool and helping to protect from the damaging effects of the sun.
And unlike metallic products, Pinnacle films won’t interfere with your GPS, keyless entry, radar detector, mobile phone, and other radio frequency technology you rely on in your vehicle
FormulaOne Pinnacle and Stratos will never interfere with GPS signals, cell phones or satellite radio!
