Which car lights to use at night

High-beam headlights are a safety device installed on all cars, yet a surprisingly large number of drivers do not use them. According to one study by the University of Michigan Transportation Research Institute (UMTRI) and the Insurance Institute for Highway Safety (IIHS), less than half of all drivers use their high-beams, even when they are appropriate.

This study also found that many drivers overestimate how much they use their high-beams, and mistakenly think they can see well enough without them. However, correctly using high-beam and low-beam headlights is a simple way of improving your safety.

It’s also the law.

When to Use Which Headlights

When to use high-beam or low-beam headlights depends on:

• Where other cars are on the road

• Weather conditions

Low-beam headlights light-up the road for a distance of about 200 feet, equivalent to half a city block.

When you cannot see farther than 200 feet using low-beams, you should switch to high-beams, unless:

• Another vehicle is within 200 feet and
