Northridge, California
Window tint rules in California set out how much light has to pass through each window on your vehicle. This Northridge guide explains how those limits are described, what happens if film is too dark, and how to think about shade and heat separately when you are choosing a film.

Film that falls outside the limits can lead to a citation. A fix-it ticket is the common outcome: the tint has to be corrected and proof of that correction submitted. Other consequences can follow, particularly where the issue is not put right.
Removing film is slower and more awkward than most people expect. Adhesive behavior varies with the film and its age, heat is often needed to lift it, and rear glass with printed defroster lines needs a careful hand. Choosing a compliant shade at the start avoids putting your glass through that process at all.
California's window tint rules treat passenger cars and multi-purpose vehicles such as vans, trucks and SUVs differently, and the limits vary by window position. The tables below set out how the rules are expressed for each vehicle type, so you can see where your vehicle fits before you choose a film.
Passenger Vehicles
Passenger vehicles, including convertibles, have set tint limits that differ from window to window across the car.

Kepler's nano-ceramic IR and IR+ films target infrared heat, so solar performance is separate from how dark the film looks. That makes lighter, compliant shades a realistic option. Compare the exact film and shade.
