How to Choose Window Tint by VLT (Visible Light Transmission)

VLT (Visible Light Transmission) shows how much visible light passes through the glass after tinting. Lower VLT = darker tint.

VLT examples

• 70% VLT — light tint
• 35% VLT — medium tint
• 20% VLT — dark tint
• 5% VLT — very dark tint

The final look also depends on factory glass, interior color, and lighting.

What to decide before choosing

• Main goal: appearance / privacy / comfort / glare reduction
• Which windows will be tinted
• Day vs night driving habits
• Local legal requirements (always check before installation)

How VLT affects the result

Higher VLT (lighter): more light in the cabin, softer visual effect, good for subtle tinting.

Medium VLT: balanced look and comfort, popular for daily-use vehicles.

Lower VLT (darker): stronger privacy, darker appearance, may be less comfortable at night for some drivers.

Common mistakes

• Choosing by photos only
• Ignoring factory glass
• Ignoring night driving comfort
• Ignoring local tint laws

Conclusion

VLT is the key parameter for tint darkness, but the best choice depends on your goal, driving conditions, vehicle glass, and local regulations.
