The reverse light in a car is typically called the "reverse lamp" or "backup light". It is a white light located at the rear of the vehicle, and it illuminates when the car is shifted into reverse gear, to provide visibility to the driver when backing up. This how-to video shows you how to change a burnt out reverse light bulb in your 1990 GMC S15. These bulbs burn out occasionally and get dimmer over time. We suggest replacing the reverse light bulbs in your 1990 S15 in pairs.

Try not to touch the glass part of the new bulb with your finger when changing the reverse light in your S15, the oil in your finger will cause that part of the reverse light bulb to burn hotter out therefore burn out quicker. Using gloves or a piece of paper towel will limit the potential of touching the bulb.
