Most furniture that has a light, ie. china hutches, entertainment centers, etc. will have a unit made by Furnlite. If your lights have quit working; first check the bulb. Then check the outlet to make sure it works (some are connected to a light switch that needs to be turned on). If all else fails, you will need to check out their catalog. If you have a touch switch that has 3 different brightness levels, if your bulbs do not burn- it usually means that the transformer (little black box) has a shortage in it. You won’t find these at Home Depot, so check out the catalog to select a match.
