a cover portion that is either transparent or translucent that encloses the light sources but which is removable to provide access to the light sources and thereby enable light source replacement when needed note that the light source bulbs would be either recessed from or in contact with the cover portion 0026 fig8 and 9 is a further variation in which the switch of the embodiments of fig1 5 and fig6 and 7 is replaced by terminals 16 18 and the flat metallic stop 14 at the end of the shackle b in the locked position the shackle may be raised from the position of fig1 to the position of fig8 constituting the amount of play in the shackle b before the flat metallic stop 14 engages where the flat metallic stop engages is where the terminals 16 18 are arranged electrical wiring to the battery and light sources is provided in the same manner as shown in the other embodiments in the case of fig4 and 6 it may be preferable to effect electrical contact to open the electrical circuit in response to the peripheral edge of the dial c moving away from the peripheral casing lip 20 after all the peripheral edge of the dial c is in contact with the peripheral casing lip 20 when the dial is in its spring biased condition while in such contact the electrical circuit is open so the power.
