3mm Bipolar Bicolor RED/ GREEN LEDS
For Model Railroads - PART # XLUGR37M

20 cents each - $17.50 per 100 - $150.00 per 1000

AS YOU CAN SEE FROM THE PICTURES IN HO SCALE, I PAINTED ABOUT 1/2 OF THE LED GRIMY BLACK, AND BENT THE LEADS AT A RIGHT ANGLE, AND PLACED IN RIGHT ON TOP OF THE BALLAST, AND SPRINKLED A LITTLE BALLAST OVER THE HOLE IN THE LAYOUT AND TO COVER WHAT LITTLE BIT OF THE LEADS SHOWED THROUGH.

Specifications and hook up info

Electrical rating 2vdc @ 20ma

Reversing the polarity causes the led to change color from green to red ……..or………… from red to green

Always use a 1K ohm resistor to limt the current to the led

Suggested Uses

DC Users
Very Simple Signals for your layout:AS SHOWN ABOVE
You could put a pair of these back to back, but wired in opposite polarity to each other, at different places on your layout, and your trains would never run against a red signal.

DC and DCC Users
Turnout Position Indicators.
Hook these up to the same 12vdc power that power your switche motors on your turnouts. You will then always know at a glance whether the turnout is lined for the mainline or the turnout.
