This 25 Watt Light Bulb is for use in most uprights which have the bayonet style socket. It is 7/8" in diameter and 2 1/8" long including its metal base. The 5/8" diameter base with two pins locks into the socket with a twist. The base has two rounded electrical contacts on its end.

For use in power nozzles which use the same type of bulb, see the 25 Watt Bulb. Later Hoover uprights use a Miniature Light Bulb which has one flat end with wires that make contact when it is pushed straight into the light socket.   For similar products see our list of Generic Parts & Components.
