Operating Voltage: 3V, AC or DC Compatible.Operating Current: 20mA
Reference Scale: 1:76~1:100,Suitable for OO scale or HO scale etc...
These Lampposts are suitable for use at supply voltages of 3V only.DO NOT use them on 12V or 16V directely to avoid damaging the LED.You must connect a resistor in series before you will use them on 12V or 16V, I will supply compatible resistors for free.
