Right now I'm at a dead stop as I wait for the glue (Krystal Klear) to dry, so I'll go over what I'm doing and using.

I'm going to be using warm white SMD LEDs, here's what they look like:


They'll be attached to the back of the light glass using Krystal Klear. After that's dried I'll wire them up to verify operation then cover the back with liquid electrical tape to make sure they stay on the light glass. It will also help prevent the light from seeping out other places. Here's how it looks now:

Got some more going, so here's the recap!

First thing I did was get the resistor attached to the white wire for the headlight:


Then I attached the blue wire from the LED to the resistor:


I then decided that now was as good a time as any to get the wires set up for the cap. So I cut the plastic off where the blue wire connects and also for the tab directly under it:



I then attached another blue wire to where the original blue wire is at. Then I attached a black wire to the plate directly under where the blue wires are attached. I used blue to match the other blue wire and black for the negative side, both wires were scraps from trimming down the decoder. I then connected the red wire for the LED to one of the blue wires. The connections should all be visible in this pic:


Lastly I tested the headlight to make sure it worked:

And we have light!

Now to work on the cap and the taillight!

I hate waiting for glue to dry (especially when have to hold the pieces being glued). To attach LEDs without having to wait you can use a 5-inute epoxy or even faster if you use Bondic or another similar UV-curable resin (5 seconds).

I wish I would've had some of that!

I have about dozen different adhesives in my arsenal.  Probably more.  It makes modeling much easier and quicker.  :)

The UV-curable glues/resins are usually available in "as seen on TV" section in most large pharmacies (Walgreens, CVS, Brooks, etc.) I also see that section in Target stores.

So, probably not gonna finish tonight, but we'll see.

Decided to start with the cap:


Then I went to twist the LED wires together before I soldered it in, and I popped the LED off the lense, so back to waiting on "glue" as I don't have anything better at the moment. Wanting something to do I decided to start sealing everything up:



I may continue some more tonight, we'll have to see.

So the SD50 is done and it's amazing! But my phone won't let me take pics at the moment. What I'm fighting with right now is figuring out how to eliminate the annoying buzz coming from, I believe, the motor. I keep reading that it's BEMF so I need to figure that out. If anyone has any insight on how to set it properly, and quickly, it would be greatly appreciated! I will also work on getting my phone up too.

Most decoders have a specific CV for dealing back EMF - check your documentation.

If you have a motor buzz from an ESU decoder the first thing is to look at the:
Quote
From Dave Heap@ LokSound Yahoo Group
From the ESU manual:
11.1.2.6. Adaptive Regulation Frequency

The decoder operates ex works with a mutable (adaptive) regulation frequency to drive the motor as precisely as possible. However, as a result some motors might show a nasty buzzing noise.
For such motors you are able to set the regulation frequency on a constant value. Set bit 4 to “1” in CV 124.

If you are using LokProgrammer or JMRI DecoderPro there is an option for "Adaptive Regulation Frequency" you can simply turn on or off and write changes to the decoder.

Another feature of the LokSound decoder is the BEMF Automatic Motor Tuning Feature. 

Quote
5.2.4.3. Automatic Adjustment

LokSound Select decoders have an Automatic Motor Tuning Feature. This feature will automatically adjust the Back-EMF in most cases. This is not meant to be a “cure all” solution. This will only get the settings close. There still may need to be some manual adjustments made.

In order to use this automatic adjustment you will first need to set CV 54 to a value of 0. Then put your locomotive on the layout and activate F1. Be sure to have plenty of clear space ahead of your locomotive. Your locomotive will quickly take off at full speed and gradually slow down to a stop while reading the motor responses. This will automatically set the load compensation in CVs 52, CV 53, CV 54, and CV 55. From here you can make any other manual adjustments if needed.

Sometimes this procedure makes the buzz worse. In that case you have no choice but to fiddle manually with the BEMF settings.  If that fails then the last choice is to turn off BEMF entirely.

Thanks for the comments guys, through messing with it I've determined that the BEMF just needs to be off. No adjustment has made a difference with its sound. In talking to ESU, their statement was that BEMF wasn't really needed and actually outdated due to how free rolling new rolling stock is nowadays.

Philip: The problem was that I had been checking my documentation and everything was so vague.

Reinhardt: That is excellent info

So if you turn BEMF off how do you get the loco to act like the prime mover has a governor.
