12 Volt Lamps. 3 Pack: Average life, 10,000 hours. Manufactured by Miniatronics Corp[. The decoderÂ’s function output voltage is typically a little less than the DCC track voltage. Most decoders have output ratings for the functions of 100 mA (milliamps) Lamps rated at 12 to 14 volts with current ratings less than 50 mA may be connected directly to the decoder. 12 to 14 Volt lamps with currents from 50 to 75 mA need a 22 ohm or 33 ohm 1/4 watt resistor in series with the lamp to protect the decoder from the high in-rush current when the lamp is first turned on. For currents from 75 to 100 mA use a 22ohm or 33 ohm 1/2 watt resistor. Lamp and resistor(one resistor for each lamp.) are wired from the common (blue wire) to the function output (white, yellow or other color function output wire).
