How to Replace Lights for Model Locomotives

Replace 12 volts bulbs in your model train locomotive with 1.5 volt LED’s. The main benefits of replacing regular 12 volt bulbs with LED’s is that it produces less heat and more light at very low speeds. It can be difficult at times to run realistic speeds with bulbs that do not produce enough light. Sometimes you must run the trains very fast to achieve proper lighting.
