Headlights grow dimmer by up to 20% over time and eventually burn out - for this reason, we recommend changing your headlights in pairs. Your headlight bulb ensures clear vision in poor weather conditions or at night. There are many different headlight bulb options in terms of brightness, color, and down-road visibility, so you can find a bulb for your repair. If you have a headlight that has started to dim or has burned out, it should be replaced as soon as possible for your safety. These bulbs have a very high voltage that runs through them, even if the battery is disconnected.
In some Cadillacs, the highbeam is the same bulb as the headlight and it is possible for the highbeam to work, but the headlight be burnt out even if they are the same bulb and vise versa. . Some Cadillacs have high intensity discharge headlights, sometimes referred to as xenon lights. Like all light bulbs, headlight bulbs will eventually burn out. .
