Hello,
the Märklin Pendolino, a realy great diesel powered multiple unit, has light bulbs for the interior lightning. Other than knowm from ICE, there is no light transmission plastic to share the light in the complete wagon. Therefore, there are two high lighted areas and the power consumption is high.

I did the conversion in two steps. The first step was, to replace the light bulbs with small LED boards with less power consumption and I used more then two of these single LED boards. In the second step, a few months later, I inserted LED stripes.

1st step: single LED boards

The advantage of these single LED boards is, that it can be used directly as replacement for the light bulb. They come with self-adhesive backside and cables soldered. You can plug them directly into the original light bulb sockets:



I soldered a second LED board parallel to one to light the interior with tree LEDs:



But as You can see, the light is not homogeneously distributed:



Therefore, here comes

2nd step: LED stripes

I bounded the LED stripes onto the circuit board. In the front area, the LED stripes were bonded to the inner side of the roof:



In the previous picture, You can see the buffer capacitor for the LED stripes, too.

The LED stripes must be splitte in the area of the holes, because there will go the mounting screw of the body:



Here, you see the ready car with the cold-white LED stripes:



And this is the motor car with the warm-white single LED boards:



Someday, I will complete the conversion for both parts, probably changing to warm-white LED stripes for both.
