Flashing ditch lights can be set up with several CV's.





Using 1.5 Volt Bulbs or LEDs

If you use 1.5 V bulbs, you must install a current setting resistor with a minimum value of 100 ohms for each bulb.

Typically a 560 ohm 1/4 watt resistor works well for a grain of rice bulb and a 250 ohm 1/4 watt resistor works well for a grain of wheat bulb.

Lower resistance values will increase the lamp brightness. If you use LED's be sure the polarity is correct when you hook them up & install a current setting resistor for each LED. Typically a 680 ohm 1/4 watt resistor is appropriate for most LEDs. We do not recommend using LEDs with FX effects because they don't give realistic lighting effects.
