These little LEDs are idea for locomotive and other model lighting.

Supplied with a 680 Ohm resistor for use at 12-18V.  With this resistor the LEDs are extremely bright.  Use a resistor with a value up to 100k Ohms to reduce the brightness.  At 100k Ohms the brightness is a warm pale yellow glow (as shown in the image of F154).

Note that the larger 0603 package is illustrated.
