Note:  Clip all extra wires at the soldered points. 
 
You have completed all connections, both wiring and 
soldering.    Carefully  double  check  the  work  against 
the pictorial diagram. 

OPERATION

 

Insert four “AA” batteries (Radio Shack No. 23

-468 

or equivalent) into the battery holder, observing plus (+) 
and  minus  (-).    Connect  the  red  lead  of  the  battery 
holder to the plus (+) terminal, and the black lead of the 
battery holder to the minus (-) terminal.  The lights will 
begin  to  blink.    The  sequential  lights  will  change 

direction if you disconnect and connect the battery.  The 
lights have other interesting effects.  They seem to blink 
faster in the absence of light.  They seem to blink faster 
of  they  are  touched  on  the  side  with  your  finger.    It  is 
possible to extend the leads of the neon lamps so that 
they  can  be  mounted  through  any  type  of  cover  you 
might  wish  to  construct.    This unit  will  give   you many 
hours of entertainment and fun showing it to your friends 
and family or just simply watching its random blinking as 
people enjoy watching the random flickering of a fire.
