We have a lot of info and photos in our vendor thread here
A few points, the Stealth Smoke Headlight Protection kits are aimed at the track / show user and are not intended for night use. This is the reason they were omitted from our night Headlight Protection kit testing photos on the site here
As for the Smoked Taillight kits, we have night testing photos of the various tint levels of the Smoked Taillight kit from both 500 and 1000 feet on the site here
. Even at 1000 feet the running lights were visible - even with the darkest material. If somebody can't see a vehicle 1000 feet away at night they likely should not be driving at night...
Let me know if you have any other questions about them.
