Add this rectifier unit to 3 volt LEDs to allow them to work with 7-19 volt AC / DCC power

This unit has:

• a full wave bridge rectifier
• An 18 volt Resistor
• Small filtering Capacitor

connect the short red wire to the red wire on your LEDs. Conntect the short black wire to the black wire on your LEDs. The two long black wires go to power.
