reusing PS1 lights

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.

Here is a 7805 circuit for LEDs.

See other posts on my blog for LED lighting

If inserting a diode string in series from a reverse board to motor the 2 ends can be tapped to drive a 1.8 volt headlamp if a diode is also in series for constant voltage directional lighting.

Marty, For PS-1 engines, the Headlight and reverse light are 1.5V 45ma GOWs. These would be connected to the PS-1 board.

The MARS light if the unit has one were 3.0V 45ma, also connected to the board.

CV board lighting is actually 6.0V bulbs 60ma. The regulator is 6 volts.

There also is a 16V 60ma bulb for track powered lighting and newer versions that are 18V. G

I'd love to know what possessed MTH to use all different voltage lights.

Lionel did too. The Mars lights on the early TMCC was a different voltage (less) than the headlights. The PS-1 had a port for LED light also. G

I think MTH carried it to a fine art. 1.5V, 3.0V, 6.0V, 12.0V, what's next?

They have 18 and 24 too Ever look at a PW lionel Bulb Chart??! G
