Newer MTH Premier observation cars have a stamped bracket to hold grain of wheat bulbs next to the markers and drumhead. Older cars rely on stray light from the overhead bulbs to illuminate the markers and drumhead which doesn’t work well.

When replacing incandescent lighting with LEDs on newer cars, I have inserted 3mm round top LEDs in the rubber grommets on the stamped brackets and I’m pleased with the results.

For older cars, I decided to make a bracket for LED marker lights using 18 gauge solid coper wire. The side markers extended inward to the middle of the car to try to catch ambient light. I broke off part of them so I could shine the LEDS on the end. The wire is malleable enough that it is easy to shape to the car and to wrap around existing posts and it’s stiff enough that once I hold it in with some hot melt glue, the lights will stay where they belong. Probably not the first time it’s been done, but it’s the first time I have done it so I thought I would share.

Here’s some pics of the stamped bracket and the copper wire bracket.

WOW, that's elaborate! :D I went the lazy man's route, I just used the bare LED and glued it to the ceiling. I also usually put heat-shrink over the sides to keep the LED from creating lighting hot-spots. In this car, the LED's are lined up with the wedge shaped markers on the side of the car, you can see one in the bottom shell below. Oddly, the wedges faced opposite directions on each side of the car.
