There may also be issues about wiring as well. Long time since I messed with one but if there are red and white lights to be replaced by LED‘s then diode protection will certainly be equired depending on direction being traveled.I should think it probably has lamps rather than LEDs?
If it does have LEDs then you will need to source bias resistors, dependent on your track voltage and the current rating of said LEDs.
As a rough check, you could try a 1K resistor on 12V. See example below....
12V
_____ = 12mA
1000
The LCE train as delivered from the factory does not include any lighting. There is an LGB accessory (66095) that allows you to replace the dummy motor block with one that includes a motor, and that comes with two pre-wired lights (one for each end) . . .the voltage of LEDs to use on this LGB lce train
Probably 19 V Edison screw ones, but they might be push in 5 V, as LGB use both....Thanks all, it definitely is second hand and does have two motors, however the lights and bulb holders look rather factory fitted.
I assumed they were LEDs however on closer look I think they are filament lamps.
