High intensity discharge, or (HID) headlights, are sometimes known as xenon headlights because they include the gas xenon, which gives the headlight a characteristic blue sheen. These bulbs are typically brighter at night than any other type of bulb.
When To Replace Headlamp
Due to years of weather conditions, your headlights, taillights, and fog lamps will begin to fade over time. Some may break, some may burn out, and still others may just be incapable of producing the necessary amount of light to see down the road. Driving without headlights and taillights is illegal. The majority of headlights should last at least two years, if not more. If you notice any mist inside your headlights or taillights, you should repair them right away to minimize electrical harm down the road. The presence of water inside the headlights indicates that there is a crack someplace that is allowing water to enter. Having your headlamp, taillight, or fog lamp changed as soon as possible may help you avoid costly problems.
