Using "Fairy" Light LEDs to light HO Passenger Cars .

A simple, compact lighting system for HO passenger cars is described using a short string of "fairy" light LEDs.   These LEDs have recently become available for use in decorative home lighting. Four of these LEDs will provide adequate illumination within the cabin of most HO passenger cars.Three methods of powering this lighting system are descibed using either track electrical pickup or an on-board 3 Volt battery. Details are outlined in the PDF file below.
