In the kit Night Vision Enhancer green LED based flashlights are widely used by hunters and others in similar activities to light up their way and alert other hunters of their presence. Green light does not interfere with the hunt, as animals are blind or indifferent to green light. Green is also a good night-vision retention color that allows one to distinguish colors such as yellow and red on maps and charts.
In the kit Night Vision Enhancer Key component of this flashlight is a 555 timer that is configured as an Astable multi vibrator generating a 50 per cent duty cycle square wave at approximately 6Hz frequency. Three green LEDs are connected at output pin 3 of 555 Timer. Switch S1 is the main on/off switch. In normal mode, LM555 IC is disabled by normally-closed (N/C) push-to-off switch S1 keeping its output low. As a result, all LEDs (D1, D2, and D3) glow continuously. On the other hand, when S2 is depressed, LM555 timer IC is enabled and all LEDs start flashing. You can also use this flashlight like a signal lamp. Flashing frequency can be varied by changing the value of capacitor.
