Everything has been tested and works. The light does come on but isn't that bright. Don't know if it is meant to be brighter. The device is in pre-owned vintage condition. Please look at photos and video for overall condition and quality. The clock face has some scuffs/marks, the clock body has some wear from use, visible in the pictures, may have other typical signs of use, but overall very clean. Flip Clock Measurements: 12" Width, 4.75" Depth, 4" Height, 6ft Power Cord.
