Model Railroading > Adding Ditch Lights to a P2K SD60M

Anyone done it?
Hints?? Picturers?? Advise??
I should add that I want them to be working ditch lights.

See my post yesterday for what I think should be helpful information.  The Ebay seller from whom I purchased my LEDs has YouTube videos walking you through the process.  Details are in the earlier thread, and several kind folks here offered great tips as well.

I used the castings from Details West on the SD60M I posted here:

I filed the back of it until it was very thin C shape that fit over a 32k (color temp) 2x3mm surface mount LED I got from Digikey. I used magnet wire to wire it up.   I glued the LED into the casting and since the back didn't fit any more, painted over it until the light didn't shine out the back.  I used a NCE D13SR decoder so put 680 ohm resistors inside the shell.  The lights are very bright so even a 1k or 1.5k would probably be ok.  I used the 2x3 mm for the ditchlights because I'd used a pair of the same LEDs for the headlights.  That way everything is the same color and brightness.

On other locos I've used smaller LEDs and fit them inside the castings.  Be sure to give a heavy coat of paint to the inside so it doesn't short out on metal castings.
