How to Dim your lights on your locomotive Ho scale

Hi everyone here you will see on how to dim your leds that you got via athearn or you custom made for your ho scale locomotive in this case you will learn how to program Tsunami 2 EMD 2 PNP decoder now the master cv for brightness on your lights is CV64 value 0-255 and you will need to use a throttle either digitrax or NCE power cab I used CV64-Value 125 or 100 to ensure the lights are more dim. Now if you want more prototypical lets say for when your train is on a siding and a train is passing you but your lights are still to bright that can blind the train crew of the oncoming train you will need to set up CV63- Value 0-255 I would say set the value of 100 or 85 that way you can make it more prototypical.
