Video Description

The video above shows you to replace the headlight in your 2003 Cadillac DeVille. Headlights grow dimmer by up to 20% over time and eventually burn out - for this reason, we recommend changing your headlights in pairs. Changing both headlight bulbs on your DeVille at the same time will allow both bulbs to have the same intensity and prevent the new headlight bulb from appearing brighter than the bulb on the opposite side. 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. These bulbs have a very high voltage that runs through them, even if the battery is disconnected. If your DeVille has this type of bulb, we do not recommend that you attempt to change it yourself.

When you change the headlight on your DeVille, it is important to not touch the glass part of the bulb with your fingers because the oil from your fingertips will cause that part of the bulb to burn hotter, which significantly shortens the life of the bulb.
