Which action helps improve night vision?

• A. Dim panel lights and clean headlights/windshield
• B. Increase panel brightness
• C. Turn on high beams during night
• D. Wear sunglasses

Answer: (A)

Night vision hinges on keeping your eyes adapted to darkness and maximizing the clarity of what you see. Dimming the interior panel lights reduces glare inside the cabin, helping your pupils stay properly adjusted to the dark and minimizing reflections from the windshield. Cleaning both headlights and the windshield removes dirt that can scatter light, so the light you rely on—both from your headlights and what you see ahead—stays as sharp as possible. Turning up panel brightness adds glare and disrupts night adaptation, high beams at night create glare for others and often don’t improve your own visibility, and sunglasses at night block too much light, making it harder to see. So dimming the panel lights and keeping headlights and the windshield clean best supports night vision.
