Well yesterday I finished installing the LEDs in the Lionel/K-Line 21” Passenger car. I apologize, Carl, that I didn’t take more pictures but I had it pretty much put back together before I remembered.
The second photo shows the difference in size between the boards. Gunrunner John’s on the left. I had to bend the heat sink that sticks up to get it to fit into the large compartment shown in third picture. I used double sided foam tape to hold it in place. The undercarriage also houses the lighting on/off switch. The LEDs are just as bright as the incandescent bulbs were.
