My understanding is that the lights in a PS1 diesel run at a voltage less than 18V, so they need the constant voltage board, or they will burn out if I hard wire them in a caboose, without the board. Is this correct?
cab lighting is 5 volts. Headlamps vary usually 1.8 volts unless it runs off track power. If you are gutting a Ps1 loco the small board for the interior lights are separate from the main boards and can be reused. Otherwise make a 7805 regulator circuit. Can also convert to LED lighting.
