Thanks for all the advice and information on installing LED lights to replace incandescent bulb strips in passenger cars. I just successfully and very economically finished wiring #29 with many more to go. They are all MTH 18" Premier cars.
With 28 cars plus an engine on the track, the amperage draw was slightly over 3. Can't wait to finish many more. Thanks again. Started out a rookie ....now I feel like a pro.
Does anyone need any 18" incandescent strips?

Sounds like things are going well for you on the conversions. Glad you got it all figured out and tackled the project. Those two guys (stan2004 and gunrunnerjohn) have given me a lot of help too, and I have learned a lot just following their advice to others. They are a great asset to the OGR forum and all of us here. I like the electronics as well as the trains, especially when something works out as well as your lighting conversions sounds like it has. It's a good feeling to have it all work out.
Glad we could assist, sounds like you're in passenger car heaven! 
I have about 35-40 to go as well, I'm about halfway done. I've taken a break for the holidays.
To Stan and Gunrunnerjohn.
Thank you! I would have never even tried to roll my own DIY project. But with the both of you and others I have the confidences to build my own. And if I run into trouble I know that I can turn to this forum and someone will give a help hand or guidance. Thanks to both of you and the other that have guide me along with my questions and helpful hints.
Happy Holidays

In all fairness, credit must be given to Shuji Nakamura who invented the blue LED which is the basis of the white LED without which we'd still be burning Amps in passenger cars. At the time, the company he worked for generously gave him a whopping $200 (two hundred) for the invention 
.
But he just received the 2014 Nobel prize in physics for his invention...and eventually received an $8 million court settlement from his now former employer.
Terrific post, stan2004. What a story!!!
Gee, even eight million doesn't seem like much for the advancement in lighting! I remember wondering for years why there were no white LED's, it seemed like such a natural thing.
John, Wait for it....Wait for it.......
Nothing is so easy as the job you imagine someone else doing.
No, I was giving him credit for something hard. But... you're right, it's easy for me to use the nice white LED's now that they exist!

When you sign on with a company (at least the USA ones I have worked for) you agree that any thing you invent is property of your employer without any compensation except your salary, unless your employer feels generous to recognize your contribution, or some agreement stipulated in your employment sign on agreement.
So surprised the Nobel winner was able to go back and win against his employer.
For my only patent all I got was a pat on the back.
