Abstract
An illumination device includes a housing and a multi-position switch for selecting various modes of operation. A security block is mounted to the housing adjacent the switch. The security block may be attached to the housing in at least two different orientations. In a first orientation, the security block prevents the switch from being in a position corresponding to certain modes (e.g., those which create a high intensity light beam). When positioned in a second orientation, the security block is attached to the housing but permits the switch to be in other or all positions, thereby permitting various modes of operation.
