How Headlights Improve Nighttime Visibility

There are a number of factors that contribute to the high nighttime accident rate in the greater Washington DC metro area, things like drowsy driving and a higher rate of impaired driving. Without a doubt, visibility is a major contributor. Let’s focus on visibility…

Dangers of Nighttime Driving

It’s said that 90 percent of our driving decisions are based on what we see. Nighttime driving has the effect of reducing 20/20 vision to the equivalent of 20/50 vision. What you could clearly see at 50 feet in daylight can’t be seen until you are just 20 feet away at night.

Accident avoidance is dependent on reaction time. Reaction time deteriorates measurably in low light conditions. One thing we can do to improve visibility is to make sure our headlights are as bright as they can possibly be.

The Importance of Headlights

Headlights dim over time. They dim so gradually that you may not notice it. Many experts suggest replacing your standard or halogen headlights once a year.

If your vehicle has standard headlights, consider upgrading to halogen lamps. They make a big difference. And there are upgrades available within the halogen category as well. This once-a-year expense is very modest compared to the safety benefits.

Some late model vehicles come with high intensity discharge – or HID – headlights. These lights should last for the life of your car. They are very bright and are clearly the best option for nighttime driving. Depending on your vehicle, you may be able to upgrade to HID headlights. Talk with your Washington DC metro area service advisor at Capitol Hill Exxon about options for your car.

What’s With Your Headlight Covers?

Another startling fact is that 90 percent of late model vehicles on the road have dirty or yellowed headlight covers. Dirty is easy to fix. Just run the window washer over the headlight cover when you stop for gas. Get those bugs and dirt off the cover. Now plastic headlight covers can yellow or become hazy over time. They can be restored to clarity with a special polishing process.

It’s also vital to keep your windshield clean and streak free when driving at night. Make sure you have plenty of washer fluid and that your windshield wipers are in good working order.

We recommend replacing wiper blades twice a year – in the spring and fall. Fall is also a good time to replace headlights so you’ll be ready for those long winter nights.
