2-light "Tortoise-friendly" dwarf signal

Same green over red signal as H-852 above, but the two LEDs are wired "back-to-back."
This makes it very easy to use with Tortoise® and similar low-current slow motion switch machines.
This signal has just two wires, simply connect it in series with a Tortoise® switch machine. No other resistors required when used in series with a Tortoise®.
