For the second marker
LED, connect second
dual LED to the same dot
locations to the left. For
opposite end LED's,
connect another pair in a
similar fashion to the dot
locations, but reverse the
colors.

Method 1: using 1
resistor in series with
the common Anode.
Method 2: using 2 resistor's in
series with each cathode.
Required to balance the led's
when both are illuminated.
When used with the RL-ADJ (item 378), a 68 ohm resistor needs
to be placed in series with the LED's as shown above.
Marker lamp wiring and limiting resistor suggestions are shown on
the back.

When connecting in this fashion, the Red and Green LED's will
operate when the track power reverses itself making dual color
marker lights possible.
3rail / AC operators can connect in the same fashion, but instead of
connecting to the rail pickup's as shown, connect to the motor
brushes. However, the e-unit must be a Dallee 518 or 400 or the
existing e-unit must be operating a DC motor.

This Incandescent White LED represents the color of light bulbs.
Input Vmax represents the maximum input voltage. The LED will
start to illuminate at a lower voltage but the current rating of the
LED will be exceeded if a lower value resistor is selected and a
higher voltage is applied.
Improper handling or powering the LED will cause permanent
damage.
