A plurality of light s'upporting brackets 20 are mounted in spaced relation' along the rod or barl 9' and elec trica'lly connectedtheretqand each bracket is provided with a'lamp socket BI-f-for receiv H 111g; in- 'thefpresent instance, the 7 four lamps 22', 23, 24 and 25."

E'ach conductor conductor and lamp when closed, see Fig. 5.
At least two of the lamps, in the illustrated embodiment the two lower lamps 25 and26,
are preferably connected in parallel so that operation of the single'switch 32 is all that is necessary to signal the presence of two empty seats. The lamp housing 7 is provided with openings or windowsi33,34. 35 and 36 op 0- site the lamps 22, 23, 24 and 25, respective y, through which they are clearlyvisible when lighted. c
'The presence of a single seat is indicated by flashing one of the single li hts 22 or 23 and it is apparent that this can be done by operating either ofthe switches controlling these respective lights, namely, switches 30 or 31, seeFig. 5. Two seats are indicated by operating the single switch 32vwhich passes current through the two lamps 24 and, 25 conin parallel. cated by lighting any three of thelamps and this can most conveniently be done by operat' the two switches 31 and 32 or 30 and 32. All ur lamps can be lighted to indicate four seats by operating the three switches simuL taneously. Itwill, of course, be understood that the flash lamp 10 is used in its ordinary manner and controlled by the usual button 14!; which is independent of the signal lamps and circuits Since the positive terminal 17 of the batter is electrically connected to the bar 19 an thus to the reflector 9', it is necessary, to prevent a short circuit, to form the connection 35 of fiber or some other insulated material, to form the casing 6 of such material, or to provide a fiber washer at the connection 36 positioned between thecasingGand the Although vI have described aiparticular arrangement of elements itcwill be apparent that various changes, additions, omissions and substitutions can be made. therein with out departing from the spirit ofzthisinverttion orv the scope of the appendedclaims.
