Tint percentage is VLT — Visible Light Transmission, the light the film lets through. Lower = darker: 70% is nearly clear, 5% is limo. The right answer for Bozeman balances three things: Montana law, night driving, and the look you want.
Start with what's legal in Montana
Montana requires front side windows to pass at least 24% of light. Since factory glass absorbs a few percent, most shops install film rated slightly above the limit so the metered result passes. Behind the driver: 14% vlt or lighter (back sides), 14% vlt or lighter (rear).
What each shade is like to live with
Altitude sun is intense and the glare off snow doubles it. Ceramic tint cuts both, blocks the UV, and keeps summer cabins bearable. With ceramic film, heat rejection comes from the technology, not the darkness — so pick the shade for law and look, and let the film handle comfort.
| VLT | The experience |
|---|---|
| 70% | Invisible; pure heat/UV rejection — the ceramic-film cheat code for strict fronts |
| 50% | Barely-there smoke; glare relief, clearly legal look |
| 35% | The classic — visibly tinted, still easy eye contact and night vision |
| 20% | Dark; strong privacy, workable at night for most drivers |
| 5% | Limo; dramatic but genuinely hard in dark parking lots |
