A light (10) and/or selector (300) may comprise a selector (300) rotatable and axially movable in a housing (20, 120) with a member (320) rotatable therewith for indicating rotational position. A projection (314) engages one or more recesses (126) when the rotatable selector (300) is proximate the housing (20, 120) and does not engage the recesses (126) when the rotatable selector (300) is distal the housing (20, 120). A spring (304) biases the rotatable selector (300) towards the housing (20, 120) so that the rotatable selector (300) must be pulled away from the housing (20, 120) against the bias of the spring (304) to disengage the projection (314) from the one or more recesses (126) and to rotate. |
