Once the sun goes down, your headlights become vital to safe driving. Although some types of headlights last longer than others, all headlight bulbs eventually fail. It’s important to notice the following symptoms of dying bulbs so you can have new headlights promptly installed at your local Nissan dealership. 

One Headlight Stops Working

When the light on one side of your car suddenly dims, one of your bulbs has probably failed. Unless it’s a wiring issue, you may need to replace both bulbs in the pair at the same time. This is because the second bulb isn’t likely to last much longer on its own and may already be losing power. Replacing bulbs in pairs helps to ensure maximum brightness and visibility at all times. 

Your Headlights Start Flickering

Headlight bulbs might start to flicker before they fail, especially if your car uses halogen bulbs. If more than one bulb is flickering, it might be caused by a failing car battery or even an alternator issue. One flickering bulb could be caused by damaged wiring or a broken or burned-out filament. You can ask a technician to test the bulb and figure it out. 

Your Headlights Grow Dimmer

All headlight bulbs start to grow dimmer for a period before they finally give up the ghost. At first, you might not notice dimming headlights; even when you do, it might be tempting to carry on driving for a while with lessened brightness. However, this is dangerous, as your visibility and reaction time to collision threats are reduced. Have any dimming bulbs replaced as soon as possible. 

Your Headlight Lenses Seem Cloudy 

Headlight problems can sometimes be caused by the lenses rather than the bulbs or wiring. As they’re situated low at the front of your car, headlight lenses naturally collect dirt, dust, insects, salt, and snow from the road. So it’s important to clean them regularly. 

Over time, lenses can also become permanently damaged by the UV rays in sunlight or by myriad little scratches. If your headlight lenses have become cloudy and cleaning doesn’t help, you might need to have them replaced. 

Your Headlight Fuse Keeps Blowing

A variety of problems can cause a headlight fuse to blow. Trouble with the electrical supply can sometimes lead to surges that blow the fuse. A blowing fuse might also indicate that the headlight itself is problematic, either faulty or improperly installed. You can ask a technician to check the bulb, headlight assembly, wiring, and harness to diagnose and fix the cause of a repeatedly blowing fuse.
