Hi Here is a coach (German Lorelei) with added end lights. It is very simply made with 2 LED purchased on ebay Germany like these https://www.ebay.de/itm/38423574...2OC%7Ctkp%3ABFBMrPjpkJdg- Pick 2 LEDs and indentify the anode and cathode by using a multimeter (Ohm position) and mark the + and minus wire (I use acrylic colors) - Drill tiny hole (0.8 mm) where the location is intended and insert the wires through the holes - Wire the LEDs in series (anode LED1 with Cathode LED2 - Wire in series a 2.2 kOhm resistor - connect to a DC source in the coach or make one with a diode and a capacitor - make a tiny box using strong black paper and make a 1.2 x 1.2 x 1.2 mm cube and glue it The result is like this on a shirt coach (Schürzenwagen der DB in the 50s)  Note: the LED is so tiny that in many cases you may glue the LEDs to the wagon's case without and imitation lantern Total cost: approx 5 EUR I hope you like it Jean |

I have been using colored LEDs with rectifier and resistor, so just connecting to track power works. I have usually not added a capacitor, as the premade LEDs have only tiny soldering points after the rectifier. https://evandesigns.com/.../lights-for-miniaturists (I just noticed that their 19V bulb version is not currently offered) |
