Q1 is operated in inverted configuration for lower leakage current. Typical on time is 0.2 sec and off lime 0.8 sec. Q1 is 2N132 and Q2 is 2N1374. Can be used as construction barricade flasher, flashing single lamp at 1 cps for up to 60 days on single battery. Use of solar-cell switch for S1, to turn off lasher automatically in daytime, will roughly double battery life in unattended locations.-Texas Instruments Inc., Transistor Circuit Design, McGraw-Hill, N.Y., 1963, p 425.
