Directional DCC headcode lights for an old Lima Class 33 - made from scratch!
Here's how I made some realistic directional light panels for my old Lima Class 33. Using surface mounted LEDs and carefully selected resistors for the perfect brightness, the video includes fitting a DCC decoder socket for easy chipping, all the electrics for the lights themselves and making the headcode blind surrounds using laminated inkjet printouts and Sugru moulding glue. Not just suitable for a Class 33, aspects of my method can also be adapted for other locos - old and new.

Thank you so much. Means a lot coming from a fellow techie ‘tuber. An awful lot of VO ends up in the iMovie edit bin, but glad it’s worth doing and appreciated. It took no time at all to realise I’m not suited to speaking on camera and that honestly takes the pressure off making the films. Thanks again. B
Your instructions and shots are exemplary! This is exactly what I needed. Thank you! Liked and subscribed.

Excellent, so glad it was helpful. Hopefully also adaptable to other locos.
Pater, enjoyed the video. The pad in the middle of the LED is (usually) for heat sinking purposes. Typically this type of LED is run at 20mA to 80mA so they need to have a way for the heat to escape. As you have connected it you are passing a much lower current than normal. So your LED shouldn't have problems for a good while.

Thanks for this. I must check the mA of the lighting output of the DCC chip. Like you say, it shouldn't be much.
