A few times I have seen a recommendation to install a 22 ohm, 1/2 watt resistor. This cuts down on the surge and lengthens light bulb life.
Many replaced the 12 volt bulb with an LED and 1k resistor.
Some do use a 1.5 volt bulb and resistor. The 1.5 volt bulbs run a lot cooler.
i have done measurements using an infra red temperature scanner.
Some DCC systems can run at a higher DCC voltage.
Failure is not an option. it comes bundled with Windows.
