This product provides an easy way to add lights to locomotives, cars and structures. Its small size (0.17″ x 0.14″) makes it easy to fit into many things. This is easy because no external dropping resistor is required and holes are provided for solder connections. Just wire this up to your DCC decoder or accessory voltages directly.
What size is the LED and is it cool or warm white?
It is a daylight type LED. Not blue like the old ones but also not particularly warm.
