Character:. Perfect for train and building layout! Made of white LEDs. Complete with wires and leds and can be illuminated. These lamp posts are only suitable for 3V supply voltages. You must place the resistor in series before you can use it on 12V or 16V. I send compatible resistors for free. Also, please apply the correct working current of 20mA to each LED. Note: Since the above size is measured manually, the actual size of the item received may be slightly different from the size above. Meanwhile, please note that due to lighting effects, monitor's brightness/contrast settings, etc. There may be slight differences in the color tone of the photos and the actual item. Product Specification: Size: As the picture shows. 5.5cm(H). Scale: 1:150-1:200, suitable for N/Z meter. Working voltage: compatible with 3V, AC or DC. Working current: 20mA. Light color: warm white Material: lamp poles with copper column. Range: 5 complete tubes and 5 resistors (not pre-soldered) for 9-18V operation.
