of parts and without requiring any soldering machining or screwing alternatively lead 32 could optionally be soldered to terminal 45 without departing from the spirit of the invention as shown in fig5 to 6 the leads 31 32 extending from led 30 are bent so that their ends are substantially parallel at a distance of approximately 7 16 in as shown in fig7 one of the leads lead 31 is threaded through tubular insulation 33 to cover the portion of the lead proximal to led 30 which portion remains in continuous contact with the battery 39 optionally lead 32 may be similarly provided with tubular insulation as shown in fig2 as shown in fig8 a battery 39 of one or more cells 40 41 in series is provided strips 70 of resiliently compressible adhesive material may optionally be placed on negative terminal 42 of cell 40 as shown in fig3 and 4 as shown in fig9 the battery 39 is placed within a section of heat shrinkable plastic tubing 60 of approximately 3 4 in length as shown in fig1 the led 30 is then inserted into the tubing 60 so that one lead 31 is disposed above negative terminal 42 of battery 39 and the other lead 32 is disposed below positive terminal 45 of battery 41 the battery 39 is oriented so that when the leads 31 and 32 contact the cells 40 41 charge flows in the proper direction to illuminate the led 30 lead 31 is disposed between strips 70 if such strips are provided as shown in fig3 and 4 as shown in fig1 a spacer 50 having a hole larger than the body of led 30.
