This invention pertainsto a multiple light such-fais a onibination tail light and spotlight or combination tail' light,` spotlightand backi''g light. l l `V The particular feature Vofthe invention resides in the construction of the lainp,-V and prticiilarly the Contact inember for provid'fv ing separate and distinct contacts betweentheconnct'ir'lgy plug and several lamps. y

Heretofore it has been the4 practice in such sti'utiirs to employ connecting plugs slid-` ably mounted with the usu'albayonet slot conI`` nectioi' having af'pir Vof spring pressed Contact pins foi* yieldingly making contact with the landps; "saidl @plugs coiitaining v spiral springs andsuitable tubes or sleevesin whichv tlie` pins are slidablyA inoiintetl, `This type of. spring ciitact has been found to'be unfit by ieason of the Sliding" pins sticking or becoming rusted or the springs losing their resiliency by "reason of exposure to the weather,

The principal object of this invention is to provide a ebiitact mein-ber which may be used in connection` with a plug having rigid contacts thereon so as not to be dependentY upon the usual sliding spring pressed contact pins mounted in the plugs. y

The `full nature of the invention will be understood from the accompanying drawings'- and the following description and claims.

Fig. 1 is a central vertical section through i a combination stop kand tail light. Fig. 2 is a. section taken on the line 2-2 thereof. Fig. `3 is a sectional view taken on vline 3 3 of Fig; 1 and'in the directionl` ofthe arrows. Fig. 4 is a central section through a modified insulation Contact illustrating an additional spring Contact. Fig. 5 is the samepas Fig. 2 showing a modified form having three con-` tacts in place of two.

In the drawings there is shown a combination tail and stoplight having a` casing l() `supported on a vehicle by the screws 12.

y Mounted in the casing there is a reflector 14 Vfor the stop light bulb 1'5, the same being posi.-

tioned within an' upper compartment which is separated from the lower compartmentV by` thepartition plate 16. 'The lowercompart'- ments-comprises a downwardly extending tongue 17 in which a, tail lamp 18 is mounted.
