Why replace bulbs two at a time?
Though replacing both headlight bulbs when only one is dimming may seem unwarranted, maintaining a consistent light output from both headlights makes the road safer for drivers, their passengers and oncoming motorists. When only one bulb is replaced, the resulting light output can be both unbalanced and unpredictable, providing inadequate lighting that can compromise driver visibility. In addition, when one bulb burns out or starts dimming, the other bulb will likely follow, forcing drivers to deal with the expense and inconvenience of getting it replaced all over again.
How else can drivers improve visibility?
In addition to properly maintaining their headlights, drivers can take the following proactive measures to make nighttime driving safer.
- Replace worn out wiper blades each season or in three-month intervals to ensure adequate visibility during rain or snow.
- Clean interior glass and mirrors to remove any film-like buildup that reduces vision and creates hazy reflections from the sun. This is especially important for smokers who smoke while driving.
- Don't hang accessories on rearview mirrors. This includes fuzzy dice, photos and other items that can be distracting and block your vision.
