I have the caboose pictured and want to basically replace the incandescent light with an LED. I have the led"s with internal resistors. I cannot find a good video specific on this. Im assuming just interchanging some wires, but wanting to check. All help appreciated.

The caboose appears to be 0 Scale. Is that correct?
The wiring for an AC track requires a diode rectifier to
convert to DC as needed by LEDs.
You would disconnect the incandescent socket
and connect wires from your LED and diodes to
the former socket terminals or wires.

Yes, it's postwar O scale:

As well as a way to drop the voltage to 4.5Vdc.

How is this any different from wiring the same led directly to track power to light my buildings excetera I have done this many times. Not challenging just curious

If the LED came with rectification and voltage regulation, then it's the same.

Running led on a car is different. A large capacitor will help with the constant voltage. If you are particular you should research the setups for passenger cars where power interruption is not desired as much.

Yeah ive seen some threads mentioning capacitor. I actually like the flicker of the light, kind of adds another dimension to the track. I put a couple in it last night, turned out well. I currently only have freight cars, and tsnk cars. I wanna get into some passenger cars.

The LED is a diode so yes it would work on a/c, being lit only on half cycles. GRJ (our moderator) has several small circuits suited for this type of application.
