Interior dome lights offer cabin illumination in a vehicle. There are usually three options for dome light switches: "on" when the doors or hatch are opened, full-time "on" and full-time "off." Before replacing the dome light bulbs, it is wise to check the switch positions to ensure the the "off" selection of the switch has not been accidentally activated. Refer to the owner's manual of the vehicle before attempting to replace the light bulbs for proper directions and correct replacement bulbs.
Inspect the dome light lens before attempting to remove it. Most covers have four small retaining tabs the hold the lens in place. On older models, there may be retaining screws that need to be removed with a Phillips screwdriver. If screws are present, remove them with the screwdriver.
Place the small slotted screwdriver into the gap between the lens and the dome light housing. Gently pry the lens to one side and look up into the gap to determine if the tabs are present on the side of the lens you chose. If not, reposition the screwdriver on another side until you locate the tabs. The tabs are usually located on two of the four sides of a dome light lens.
Pry one of the tab sides of the lens carefully away from the dome light housing using the screwdriver. The dome light lens usually has some flexibility to it, but you can easily crack or damage the lens or the tabs.
Use the screwdriver as a leverage point and once the tabs on one side of the lens are exposed, pry the lens downward with the screwdriver. This will release the tabs on the side of the screwdriver, the lens will drop down and release the other retaining tabs on the opposite side. Remove the lens.
Remove the bulbs from the sockets. There are a variety of different bulbs used for interior lighting. Some bulbs may require turning to extract them from the socket, while others may simply need to be popped out of the retaining clips.
Insert the replacement bulb(s) and test before replacing the lens.
Replace the lens by inserting the retaining tabs on one side and using the screwdriver to pry it into position carefully.
