Window Tint Shade Guide: 70% vs 50% vs 35% vs 20% vs 5% VLT Explained

Updated: Mar 25


What Do Window Tint Percentages Mean? A Complete Shade Guide

Window tint percentages refer to Visible Light Transmission (VLT) — the amount of visible light that passes through the film. A lower percentage means a darker tint. For example, 5% VLT (often called "limo tint") blocks 95% of visible light, while 70% VLT is nearly clear and allows 70% of light through. Understanding these percentages is essential for choosing the right look and staying legal in California.

At Rapid Window Tinting in Los Angeles, we install every shade level daily. Here's our complete guide to help you choose the perfect tint percentage for your vehicle.

70% VLT: The Nearly Clear Legal Front Window Tint

70% VLT is the lightest window tint shade and the only percentage legal for front side windows in California. While it looks nearly invisible, don't underestimate its performance. XPEL XR Plus in 70% VLT still blocks up to 98% of infrared heat and 99% of UV rays. You get massive heat rejection and sun protection without any visible change to your windows.

Best for: Front driver and passenger windows in California (legal requirement). Also ideal for drivers who want heat and UV protection without any visible darkening. Popular on luxury vehicles where owners want a factory-clean look with maximum protection.

Does Darker Tint Block More Heat?

This is a common misconception. With ceramic window tint, the heat rejection is nearly identical regardless of shade. XPEL XR Plus blocks up to 98% of infrared heat whether you choose 70% VLT or 5% VLT. The darkness (VLT percentage) only controls how much visible light passes through — not how much heat is blocked.

This means you can get incredible heat rejection even with the lightest legal tint on your front windows. That's one of the biggest advantages of premium ceramic tint over cheaper dyed films, where darker shades do absorb more heat.

What does VLT mean for window tint?

VLT stands for Visible Light Transmission, which measures the percentage of visible light that passes through the window tint film. A lower VLT number means a darker tint — for example, 5% VLT (limo tint) is very dark while 70% VLT is nearly clear. At Rapid Window Tinting in Los Angeles, we carry XPEL PRIME films in all VLT levels from 5% to 70% to match your preferences.

What is the darkest legal window tint in California?

In California, the darkest legal tint for front side windows is 70% VLT, while rear side windows and the back windshield can be any darkness. The front windshield allows a non-reflective tint strip on the top 4 inches. At Rapid Window Tinting in Los Angeles, we help customers choose the darkest legal options while maximizing heat rejection with XPEL ceramic technology.

Can you see through 20 percent window tint at night?

Yes, you can see through 20% VLT window tint at night from inside the vehicle, though visibility is slightly reduced compared to lighter tints. Quality ceramic tints like XPEL PRIME maintain better optical clarity than cheap dyed films, even at darker shades. Visit Rapid Window Tinting at 5300 Sunset Blvd Suite 6, Los Angeles CA 90027 to view tint samples on actual glass before deciding.

What is the difference between 35% and 20% window tint?

35% VLT allows more light in and provides a medium-dark appearance, while 20% VLT is noticeably darker and offers more privacy. Both levels provide excellent UV protection when using ceramic film. At Rapid Window Tinting in Los Angeles, 20% is our most requested shade for rear windows, while 35% is popular for customers who want privacy without a very dark look. Call (323) 358-2520 to see samples in person.
