What the law says
Smoked or tinted film on headlights and taillights is illegal in Idaho. Headlights must emit white light and taillights must show red at the required visibility distance, and tint that dims or discolors them violates those requirements. Taillights must show red plainly visible at 500 feet. No state expressly permits smoked lamp film; the violation is the loss of required color or visibility distance, which any meaningful tint causes.
