The picture shows this Flintstones Barney Rubble Night Light. The gray item at the bottom is the switch. It resembles a wheel from one of the Flintstones cars. The light does work and uses a Christmas bulb. Right now there is a blue bulb in it. I see no HannaBarbera marking or date but it is believed to be from the 1960's or 1970's. It measures 4-1/2" tall and is in mint condition.
