Hi there soy steam locomotive has a working rear light and I was wondering how I go about hooking it up for directional lighting any help would be great
Thankyou.
Thankyou.
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.What size diode?
