A light and/or selector may comprise a selector rotatable and axially movable in a housing with a member rotatable therewith for indicating rotational position. A projection engages one or more recesses when the rotatable selector is proximate the housing and does not engage the recesses when the rotatable selector is distal the housing. A spring biases the rotatable selector towards the housing so that the rotatable selector must be pulled away from the housing against the bias of the spring to disengage the projection from the one or more recesses and to rotate. |
