Standard way for a straight DC powered locomotive would be to put a diode in series with the lamp.

What size diode?
Depends on the lamp, I use 3 volt LEDs so I use a 700ish ohm resistor instead of a diode. Resistor on the + leg for one direction and a resistor on the - leg for the other direction.
