The video above shows you to replace the headlight in your 2002 Infiniti Q45. 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 Q45 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 Infinitis, 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 Infinitis 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 Q45 has this type of bulb, we do not recommend that you attempt to change it yourself.
When you change the headlight on your Q45, 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.
On many cars, the high beam bulb runs at reduced power during the day - check 'em and change 'em!1998 Infiniti Q45 4.1L V8
