Symptoms

- Other rear lights (taillights, brake lights) work normally

- Bulb housing is small and located near the plate
Likely causes
- CommonBurned out license plate light bulbThese small bulbs wear out like any other and are easy to overlook since they're not very bright.
- PossibleCorroded socket or connectorMoisture exposure near the rear bumper can corrode the small housing over time.
- PossibleBlown fuse shared with other lightsSome vehicles group the license plate light with other circuits on one fuse.
What to do
- Locate the license plate light housing, usually a small lens above or beside the plate.
- Gently pry the lens cover off with a small flathead screwdriver or trim tool.
- Remove the small bulb and inspect it for a broken filament or dark glass.
- Install a new bulb of the correct size, usually a small wedge-base type.
- Check the socket for corrosion and clean gently if the new bulb doesn't light up.
- Check the fuse box if replacing the bulb doesn't fix it, since it may share a fuse with another light.
- Snap the lens cover back into place and test the light.
- Get this fixed promptly, since many areas require a lit license plate at night.
