Dennis,
Back when the LED replacements 1st came out I replaced all my old 711/072 and 022 switches and controller light bulbs with the LED's to help keep the massive power draw down on my office/gameroom multi level layout. The LED's worked great and I also put them in some of the older Lionel rolling stock, Fish Tank car, ect. At the time Scott's Odds & Ends supplied them to me, later T&C Hobbies that the men have posted for you, delivered slightly different ones to me. I highly recommend them, although they now cost more money than when they 1st came on the market. Great product no doubt about it.

The LED's in the picture below came from Scott when they 1st hit the market.
