Ensure that the glass covering your headlamps is not frosted or cracked. When headlight lenses are frosty, it dims the brightness of the headlight bulbs, making them appear hazy and making the light emitted less effective.
Test the brightness of your headlights after dark. Park your car facing a wall on a flat level surface face. Ensure you are just five feet away from the wall when testing our headlights. Go into the car and turn on the switch for the headlights. It is a switch located at the left hand side directly behind the steering wheel. Activate the headlights by turning the switch in a forward position.
Observe Lighting Quality
Turn on your headlights and look at the light from your headlights reflecting on the wall. Observe the appearance of the light by looking for circles of soft white or bright light that is evenly aligned on the wall facing the car. If the light appears dim or yellow, this is an indication that the bulb needs to be changed. The circles of light should be bright or soft white, not yellow or dim, and the circles should be even and aligned straight forward on the wall.
Replace Bulbs & Lenses
Change the headlight bulbs if the light appears to be dim or yellowish. Both bulbs should be replaced at the same time, even if there is a defect in one of the bulbs. Replace headlight lenses if they have a cloudy appearance. Glass lenses are better for visibility than plastic lenses. Plastic lenses often make the light appear dim and hazy, and this can affect your visibility while driving.
